This article is reviewed for clinical accuracy. Occasional, incidental dirt eating in a healthy dog rarely requires treatment. Compulsive or daily dirt ingestion, or dirt eating accompanied by vomiting, weight loss, lethargy, or other signs of illness, warrants a veterinary evaluation including a complete blood count, serum chemistry profile, urinalysis, and fecal examination to rule out nutritional deficiencies, gastrointestinal disease, and endocrine disorders.

Key Takeaways

  • Eating non-food substances including dirt, clay, sand, rocks, and soil is classified as pica, a term derived from the Latin word for magpie (a bird known for eating indiscriminately). Geophagia specifically refers to eating earth or soil. In dogs, pica and geophagia have multiple possible causes that span behavioral, nutritional, gastrointestinal, and systemic disease categories. Identifying the specific driver matters because behavioral geophagia responds to environmental enrichment and management, while geophagia driven by iron-deficiency anemia, inflammatory bowel disease, or hepatic encephalopathy requires specific medical treatment of the underlying condition.
  • The most clinically relevant causes of dirt eating in dogs are: (1) Nutritional deficiency, particularly iron, zinc, or mineral deficiencies, in dogs on poor-quality or home-cooked diets that are not nutritionally complete and balanced; (2) Gastrointestinal disease causing nausea or abdominal discomfort (gastritis, inflammatory bowel disease, exocrine pancreatic insufficiency), where the dog seeks to eat dirt as a way of modifying gut sensation or inducing vomiting; (3) Anemia (iron-deficiency anemia, chronic disease anemia) where mineral-seeking behavior drives geophagia; (4) Endocrine disease (hyperadrenocorticism/Cushing’s disease, diabetes mellitus) causing polyphagia and indiscriminate eating; (5) Hepatic encephalopathy from chronic liver disease, where altered mentation and abnormal appetite regulation drive aberrant eating behaviors; (6) Behavioral causes including boredom, anxiety, compulsive disorder, or attention-seeking in dogs with inadequate exercise and mental stimulation.
  • The primary danger of dirt eating is ingestion of toxins and pathogens present in soil. Soil can harbor intestinal parasites including Toxocara canis (roundworm) eggs (which can remain infective in soil for years), hookworm larvae (Ancylostoma caninum), Giardia cysts, Cryptosporidium oocysts, and Clostridium botulinum spores. Soil in areas treated with herbicides, pesticides (organophosphates, rodenticides), or heavy metals (lead, arsenic from old paint or industrial contamination) poses toxicological risk. Dogs that eat large amounts of dirt can develop gastrointestinal obstruction from soil impaction, particularly sand impaction of the intestinal lumen, which presents as vomiting, abdominal pain, and obstipation requiring veterinary intervention.
  • Diagnostic workup for a dog eating dirt regularly: complete blood count (CBC – check for anemia, MCV for iron deficiency; microcytic, hypochromic anemia suggests iron deficiency; normocytic normochromic anemia suggests chronic disease), serum chemistry profile (liver enzymes, BUN, creatinine, glucose, albumin, total protein), urinalysis, fecal flotation and fecal antigen testing (Giardia, Cryptosporidium), serum folate and cobalamin (B12) to screen for small intestinal malabsorption, TLI (trypsin-like immunoreactivity) to screen for exocrine pancreatic insufficiency (EPI), and ACTH stimulation test or low-dose dexamethasone suppression test if hyperadrenocorticism is suspected. Serum zinc and copper levels if a specific mineral deficiency is suspected.
  • Treatment is directed at the specific identified cause. For nutritional causes: transition to an AAFCO-complete commercial diet or add a veterinary-recommended mineral supplement; for EPI: porcine pancreatic enzyme powder supplementation (Viokase-V 1-2 tsp per cup of food); for IBD: dietary management (hydrolyzed protein or novel protein diet trial minimum 8-10 weeks) or immunosuppression (prednisolone 1-2 mg/kg/day tapering, or budesonide 3 mg/m2/day); for behavioral pica: increased physical exercise, food puzzle toys, anti-anxiety medication (fluoxetine 1-2 mg/kg PO SID, clomipramine 1-3 mg/kg PO BID) in compulsive cases.

Watching your dog root their nose into the garden and actively eat fistfuls of soil is bewildering at first glance. Dogs are not herbivores, and soil has no obvious caloric value. Yet dirt eating is one of the more commonly reported unusual behaviors in dogs across all breeds and ages. The behavior can be a brief exploratory quirk in an otherwise healthy puppy, or it can be a persistent, compulsive behavior signaling an underlying medical problem that genuinely needs attention. The key is knowing how to distinguish the two.

Defining the Behavior: Pica and Geophagia

Pica is the veterinary and medical term for the persistent ingestion of non-nutritive, non-food substances. It encompasses eating soil (geophagia), rocks (lithophagia), feces (coprophagia), grass, cloth, wood, plastic, and other non-food materials. These behaviors are distinguished from normal exploratory mouthing (puppies investigate objects with their mouths as part of normal development) and from incidental ingestion during play by their persistence, frequency, and the active seeking of the non-food substance. A dog that occasionally sniffs and accidentally ingests a small amount of soil while investigating a scent is not exhibiting pica. A dog that actively seeks out, mouths, and deliberately swallows soil daily, or in large amounts, is.

Geophagia specifically has been observed across mammalian and avian species including primates, elephants, parrots, and livestock. In wild and free-ranging species, clay and mineral-rich soils are selectively consumed as a source of minerals (calcium, iron, sodium) or to bind toxins in the gut (clay acting as an adsorbent). These ancestral drivers may explain some of the geophagia observed in domestic dogs, particularly when nutritional needs are unmet by the commercial diet.

Cause 1: Nutritional Deficiency

A dog on a nutritionally incomplete diet may seek missing minerals through geophagia. The nutrients most commonly implicated:

  • Iron: Iron-deficiency anemia causes geophagia in multiple species including humans (pagophagia in iron deficiency, or compulsive ice eating, is the human equivalent). In dogs, iron deficiency is most common in puppies on all-milk diets, dogs with chronic blood loss (gastrointestinal ulceration, heavy flea infestation, hookworm), and dogs on home-cooked diets without supplementation. CBC findings: microcytic (small red cells, low MCV) and hypochromic (low MCHC) anemia; low serum iron; low ferritin; elevated total iron-binding capacity (TIBC). Treatment: identify and correct the source of blood loss, supplement with ferrous sulfate 100-300 mg PO SID until CBC normalizes.
  • Zinc: Zinc deficiency is most recognized in Arctic breeds (Siberian Husky, Alaskan Malamute) that have higher zinc requirements, and in dogs on high-phytate diets (excess grain-based diets) that impair zinc absorption. Signs of zinc deficiency: facial and footpad dermatitis, crusting around the face, eyes, and muzzle, poor wound healing, immune dysfunction, and aberrant appetite including pica. Diagnosis: serum zinc level below 0.7 mcg/mL suggests deficiency. Treatment: zinc gluconate or zinc methionine supplementation under veterinary guidance; zinc toxicity (hemolytic anemia) occurs at doses above therapeutic range, so supplementation requires monitoring.
  • Calcium, phosphorus, magnesium: Imbalances in calcium-phosphorus ratio from unbalanced home-cooked diets or raw meat-only diets (high phosphorus, low calcium) can drive mineral-seeking behavior; all-meat raw diets without bone or calcium supplementation are calcium deficient and may predispose to pica in addition to causing metabolic bone disease (nutritional secondary hyperparathyroidism).

Solution: transition to or confirm the dog is fed an AAFCO-complete and balanced commercial diet appropriate to their life stage. If feeding a home-cooked diet, use a recipe formulated by a board-certified veterinary nutritionist (DACVN) through a service such as BalanceIT or PetDiets rather than adapting a recipe from an unverified internet source.

Cause 2: Gastrointestinal Disease and Nausea

Dogs with nausea, acid reflux, or gastrointestinal discomfort frequently eat grass and may also eat dirt. The hypothesis is that ingesting coarse plant material or alkaline soil modifies the gastric environment or triggers vomiting to relieve nausea. Conditions that commonly cause nausea-driven pica in dogs:

  • Gastritis (acute or chronic): Gastric mucosal inflammation from dietary indiscretion, NSAID use, Helicobacter infection, or idiopathic causes; signs include intermittent vomiting (often bile-tinged), lip licking, grass or dirt eating, reduced appetite; diagnosis by endoscopy and gastric mucosal biopsy; treatment: omeprazole 0.7-1 mg/kg PO SID (PPI for acid suppression), maropitant (Cerenia) 1 mg/kg PO or SC SID for nausea, bland diet (boiled chicken and white rice) during acute episodes
  • Inflammatory bowel disease (IBD): Chronic immune-mediated inflammation of the small intestinal mucosa causing malabsorption, protein-losing enteropathy, chronic vomiting, diarrhea, and weight loss; pica is a non-specific sign; diagnosis requires intestinal biopsy (endoscopic or surgical); treatment: hydrolyzed protein diet or novel protein elimination diet trial first; immunosuppression with prednisolone 1-2 mg/kg/day tapering over months, or budesonide 3 mg/m2/day (less systemic immunosuppression) for refractory cases; cobalamin supplementation (cyanocobalamin 250-1500 mcg SC weekly for 6 weeks, then monthly) for IBD-associated cobalamin deficiency
  • Exocrine pancreatic insufficiency (EPI): Deficiency of pancreatic digestive enzymes (lipase, protease, amylase) causing maldigestion and malabsorption; classic triad of polyphagia, voluminous pale/greasy diarrhea, and weight loss despite good appetite; affected dogs may eat dirt, feces, and anything else available; breeds predisposed: German Shepherd Dog (most common), Rough Collie, Chow Chow; diagnosis: serum TLI (trypsin-like immunoreactivity) below 2.5 mcg/L confirms EPI; treatment: porcine pancreatic enzyme powder (Viokase-V or Pancrezyme) 1-2 tsp per cup of food mixed in and pre-incubated 20 minutes before feeding; cobalamin supplementation and small intestinal bacterial overgrowth (SIBO) treatment with tylosin 25 mg/kg PO SID or metronidazole 10-15 mg/kg PO BID as needed
  • Portosystemic shunt (PSS) and hepatic encephalopathy: Vascular anomaly allowing portal blood to bypass the liver, causing elevated blood ammonia and hepatic encephalopathy; affected dogs show behavioral changes, apparent mentation changes (staring into space, apparent blindness), seizures, ptyalism (drooling), and abnormal eating behaviors including pica; young dogs of predisposed breeds (Yorkshire Terrier, Maltese, Miniature Schnauzer, Irish Wolfhound, German Shepherd); diagnosis: fasting and 2-hour post-prandial bile acids; elevated fasting bile acids above 25 mcmol/L or post-prandial above 25-50 mcmol/L; definitive diagnosis by CT angiography or nuclear hepatic scintigraphy; treatment: surgical attenuation (ameroid constrictor, cellophane banding) for extrahepatic shunts; medical management with lactulose 0.5 mL/kg PO BID-TID and dietary protein restriction for non-surgical candidates

Cause 3: Anemia

Iron-deficiency anemia is the classic anemia driving geophagia. However, any significant anemia may reduce tissue oxygen delivery enough to produce lethargy, weakness, and aberrant appetite. Anemia in dogs has multiple causes beyond iron deficiency: immune-mediated hemolytic anemia (IMHA), chronic kidney disease anemia, bone marrow suppression from tick-borne disease (Ehrlichia, Anaplasma), or blood loss from GI ulceration. CBC is the essential first step in evaluating a dirt-eating dog; even a mild unexplained anemia warrants further investigation for underlying disease.

Cause 4: Endocrine Disease

Hyperadrenocorticism (Cushing’s disease) causes polyphagia and polydipsia in dogs; affected dogs eat indiscriminately and may eat dirt along with other non-food items. Excess cortisol drives the polyphagia by reducing central satiety signaling. Poodles, Dachshunds, Beagles, Boxers, and Boston Terriers are predisposed to pituitary-dependent hyperadrenocorticism. Diagnosis: low-dose dexamethasone suppression test (LDDST) or ACTH stimulation test; basal cortisol alone is not diagnostic. Treatment: trilostane 1-3 mg/kg BID (titrated to maintain ACTH-stimulated cortisol between 2-7 mcg/dL) or mitotane (o,p’-DDD) protocol. Diabetes mellitus also causes polyphagia and indiscriminate eating; diagnosis by fasting hyperglycemia (above 250 mg/dL consistently) and glucosuria.

Cause 5: Behavioral Pica

In the absence of a medical cause, dirt eating is classified as behavioral pica. Contributing factors:

  • Boredom and insufficient enrichment: Dogs that spend long periods alone without mental stimulation or physical exercise develop outlets for pent-up energy; digging and eating dirt can provide sensory stimulation and a rudimentary activity; highest risk in high-energy breeds (Border Collie, Belgian Malinois, Jack Russell Terrier, Weimaraner) that are underexercised
  • Anxiety and stress: Separation anxiety, noise phobia, and generalized anxiety disorder in dogs produce stereotypic behaviors and oral displacement activities; some anxious dogs mouth, chew, and swallow non-food items as a self-soothing behavior; the anxiety diagnosis is supported by a history of other anxiety signs (panting, pacing, destructiveness, inappropriate elimination when alone)
  • Compulsive disorder: Canine compulsive disorder (CCD) is the canine equivalent of obsessive-compulsive disorder; repetitive, out-of-context behaviors performed intensely and interfering with normal function; dirt eating that is compulsive, escalating, and resistant to redirection may qualify; breed predispositions for CCD: Bull Terriers (spinning, tail chasing), German Shepherd Dogs (flank sucking), Doberman Pinschers (flank sucking, blanket sucking); treatment: SSRIs (fluoxetine 1-2 mg/kg PO SID) or tricyclic antidepressants (clomipramine 1-3 mg/kg PO BID) as pharmacological support plus behavior modification with a veterinary behaviorist
  • Attention-seeking: A dog that has learned that eating dirt produces a dramatic owner response (scolding, running to stop the behavior, interaction) may continue the behavior to elicit attention; management: remove the reward (avoid running over excitedly), interrupt calmly, and redirect to an acceptable behavior, then reward the acceptable behavior

Risks of Eating Dirt

Diagnostic Workup

Test What It Screens For
CBC with differential Iron-deficiency anemia (microcytic hypochromic), IMHA, chronic disease anemia, thrombocytopenia (tick-borne)
Serum chemistry profile Liver disease (elevated ALT, ALP, bile acids), renal disease, hyperglycemia (Cushing’s/diabetes), hypoproteinemia (EPI, IBD)
Urinalysis Glucosuria, proteinuria, dilute urine (Cushing’s, renal disease)

Serum TLI Exocrine pancreatic insufficiency (TLI below 2.5 mcg/L)
Serum cobalamin (B12) and folate Small intestinal malabsorption (EPI, IBD); cobalamin deficiency; low B12 suggests distal SI disease; low folate suggests proximal SI disease
Pre- and post-prandial bile acids Portosystemic shunt, hepatic dysfunction
LDDST or ACTH stimulation test Hyperadrenocorticism (Cushing’s disease)

Red Flags: When Dirt Eating Warrants Immediate Veterinary Attention

  • Dog eating dirt daily or in large quantities: any dog that actively and repeatedly seeks out soil and ingests it in more than incidental amounts should have a medical evaluation; the risk of parasitic infection, toxin ingestion, and GI obstruction increases with the amount consumed, and a medical cause is plausible in any dog with compulsive geophagia
  • Dirt eating accompanied by weight loss, lethargy, vomiting, or diarrhea: these signs indicate a medical problem is driving the behavior; same-day or next-day veterinary evaluation is appropriate; the combination of vomiting, weight loss, and dirt eating is a classic presentation of EPI in German Shepherd Dogs
  • Known or suspected exposure to contaminated soil (pesticide-treated garden, industrial land, old paint, or an area with confirmed rodenticide use): if a dog ingests soil from a potentially contaminated source, contact your veterinarian or the ASPCA Animal Poison Control Center (888-426-4435) immediately; do not wait for symptoms; rodenticide-contaminated soil is a particular concern as symptoms of anticoagulant poisoning (internal hemorrhage) are delayed 3-5 days after ingestion
  • Young dog of a predisposed breed (Yorkshire Terrier, Maltese, Miniature Schnauzer) with bizarre behavior changes, drooling, apparent confusion, or seizures in addition to pica: suggests portosystemic shunt with hepatic encephalopathy; this is an urgent presentation requiring same-day evaluation
  • Suspected or confirmed intestinal obstruction from soil/sand impaction: a dog that has eaten a large amount of sand or soil and then becomes lethargic, stops eating, vomits repeatedly, or shows signs of abdominal pain requires emergency veterinary evaluation; abdominal radiographs will show radio-dense material in the intestinal lumen confirming impaction; surgical removal may be required

Age-Specific Considerations

Puppies (Under 1 Year)

  • Exploratory mouthing and occasional dirt eating is normal developmental behavior in puppies under 6 months; puppies explore the world with their mouths and incidental ingestion of small amounts of soil during sniffing and play is expected and not a cause for concern; the behavior usually decreases as the puppy matures
  • Persistent or escalating dirt eating in a puppy beyond 6 months warrants evaluation; hookworm and roundworm infection (acquired from contaminated soil) is common in puppies and produces diarrhea, anemia, and poor condition; ensure puppies are on a complete deworming schedule (pyrantel pamoate 5 mg/kg PO at 2, 4, 6, and 8 weeks; fenbendazole 50 mg/kg PO daily x3 days for whipworms; preventive with monthly heartworm preventives that also control intestinal parasites)
  • Home-cooked or raw diets given to puppies without proper formulation by a veterinary nutritionist are a common cause of nutritional deficiency and subsequent pica; growing puppies have higher and more specific nutritional demands than adults; an AAFCO-complete diet formulated for large breed growth (for large breeds) or all life stages is the safest starting point

Adult Dogs (1-8 Years)

  • New onset of dirt eating in a previously non-pica adult dog is more likely to have a medical cause than dirt eating in a puppy; it warrants a veterinary evaluation rather than behavioral management alone; the most common medical causes to investigate first in adult dogs are GI disease (IBD, EPI, gastritis), endocrine disease (Cushing’s, diabetes), and anemia
  • Adult working or performance dogs (herding breeds, sporting breeds) with high exercise demands that are fed maintenance-level rations may develop relative nutritional deficiencies if caloric and micronutrient intake does not match their energy expenditure; these dogs may exhibit pica; increasing food quantity to match activity level, or transitioning to a performance diet with higher nutrient density, can resolve the behavior
  • Adult intact female dogs may develop pica during pregnancy or pseudopregnancy from altered nutritional demands or hormonal influence; ensure gestating or lactating bitches are fed a diet formulated for growth/reproduction (higher protein, calcium, and caloric density than maintenance diets)

Senior Dogs (8+ Years)

  • New onset of pica or dirt eating in a senior dog should be treated as a medical symptom until proven otherwise; hyperadrenocorticism peaks in middle-aged to older dogs (7-10 years); GI neoplasia (intestinal lymphoma, adenocarcinoma) causing malabsorption and nausea is more common in seniors; hepatic disease from chronic cholangiohepatitis or neoplasia can cause hepatic encephalopathy and associated behavioral changes
  • Cognitive dysfunction syndrome (CDS) in dogs aged 9 years and older can produce behavioral changes including abnormal appetite, disorientation, and repetitive behaviors that may include eating non-food items; CDS is a diagnosis of exclusion after medical causes are ruled out; treatment: dietary management with antioxidant-enriched senior diets, selegiline (Anipryl) 0.5-1 mg/kg PO SID, and environmental enrichment
  • Senior dogs on long-term medications (phenobarbital for epilepsy, prednisone for immune-mediated disease) have drug-induced polyphagia as a known side effect; dirt eating as part of indiscriminate appetite increase in these dogs may be medication-driven; discuss medication management and dose adjustment with the prescribing veterinarian

Myths About Dogs Eating Dirt

Myth

Dogs eat dirt to settle an upset stomach, and it always helps, so it’s fine to let them do it.

Fact

The idea that dogs self-medicate by eating dirt or grass has some biological precedent, but allowing the behavior is not without risk. Soil may contain parasite eggs, pesticide residues, or heavy metals that are harmful regardless of how the soil makes the dog feel momentarily. More importantly, if a dog is regularly eating dirt because of nausea from an underlying GI condition like IBD or EPI, treating the symptom (letting them eat dirt) while the underlying disease progresses is counterproductive. A dog with frequent nausea needs veterinary investigation and treatment, not permission to self-soothe with soil.

Myth

Only malnourished dogs eat dirt; if my dog eats well, it must be behavioral.

Fact

A dog can eat a full bowl of food twice a day and still have a deficiency if the diet is nutritionally unbalanced, if the dog has a condition impairing nutrient absorption (EPI, IBD, SIBO), or if there is a specific nutrient requirement that the diet does not meet (zinc in Arctic breeds). Conversely, a well-fed, apparently healthy dog can have behavioral pica from boredom or anxiety. Dietary adequacy does not rule out a medical cause, and neither does a good appetite. Investigation is needed regardless of feeding history.

Myth

Punishing the dog when it eats dirt will stop the behavior.

Fact

Punishment is not effective for pica driven by a medical cause, because the compulsion to eat the substance is driven by a physiological or psychological state the dog cannot control voluntarily. Punishing a dog for eating dirt when the behavior is caused by iron-deficiency anemia, hepatic encephalopathy, or anxiety does not address the driver of the behavior and causes additional stress. For behavioral pica without a medical cause, redirection and reinforcement of incompatible behaviors (asking the dog to sit, come, or leave it and rewarding these alternative behaviors) is far more effective than punishment. Addressing the root cause (increasing exercise, treating anxiety, providing enrichment) produces durable behavior change.

Frequently Asked Questions About Dogs Eating Dirt

Why is my dog eating dirt all of a sudden?

Sudden onset dirt eating in a dog that previously did not exhibit this behavior is more likely to have a medical cause than a long-standing behavioral pattern. The most common sudden triggers include new gastrointestinal symptoms (nausea from gastritis, IBD, or EPI), onset of anemia, endocrine disease (Cushing’s disease, diabetes), or neurological/behavioral change from anxiety or liver disease (hepatic encephalopathy). A veterinary evaluation with basic bloodwork (CBC, chemistry, urinalysis) and fecal testing is the appropriate next step for new-onset dirt eating.

Is it dangerous for dogs to eat dirt?

It depends on the amount and the soil. Small, incidental ingestion of clean garden soil during sniffing and playing is unlikely to cause harm in a healthy vaccinated and dewormed dog. Regular or large-quantity dirt eating carries real risks: intestinal parasite infection (roundworm, hookworm, Giardia from soil), potential pesticide or heavy metal toxin exposure, dental enamel erosion from grit, and gastrointestinal obstruction from sand or soil impaction. The behavior should be discouraged, and if it is persistent or compulsive, a veterinary evaluation is warranted.

Can dirt eating cause worms in dogs?

Yes. Soil is a reservoir for infective stages of common canine intestinal parasites. Toxocara canis (roundworm) eggs can remain viable and infective in soil for years; Ancylostoma caninum (hookworm) infective L3 larvae are present in moist warm soil; Giardia cysts survive in soil especially in wet conditions. A dog regularly eating dirt is at elevated risk for intestinal parasitism regardless of whether they are on monthly preventives (most monthly heartworm preventives do not protect against whipworms or Giardia). Annual or semi-annual fecal testing and targeted deworming is appropriate for dogs with geophagia.

How do I stop my dog from eating dirt?

First, rule out a medical cause with a veterinary examination and basic diagnostics (CBC, chemistry, fecal). If medical causes are excluded, behavioral management is the focus: increase physical exercise to reduce boredom; provide food puzzle toys and enrichment activities to occupy the dog’s mind; use a “leave it” command trained with positive reinforcement; supervise outdoor time and interrupt dirt-eating calmly, then redirect to an appropriate activity. For compulsive cases, a veterinary behaviorist consultation and possible pharmacological support (fluoxetine 1-2 mg/kg SID) may be needed.

Does dirt eating mean my dog is missing something in their diet?

It might. Nutritional deficiency, particularly iron, zinc, or an imbalanced calcium-phosphorus ratio from an unbalanced home-cooked or raw diet, is a recognized cause of pica and geophagia. However, GI disease causing malabsorption, endocrine disease, and behavioral causes can also drive dirt eating in dogs on complete and balanced commercial diets. Nutritional deficiency as the sole cause is more likely in dogs on home-cooked, raw, or unconventional diets that are not formulated to meet AAFCO standards. Serum mineral panels and dietary analysis by a veterinary nutritionist can confirm or rule out a dietary deficiency.

What should I do if my dog eats dirt from a treated garden?

If you know or suspect the soil was recently treated with herbicides, pesticides, rodenticides, or fertilizers, contact your veterinarian or the ASPCA Animal Poison Control Center (888-426-4435) immediately. Provide the product name and active ingredient if known, and the approximate amount of soil the dog ate. Do not induce vomiting without veterinary direction; some toxins cause more harm if vomited. For anticoagulant rodenticide exposure, symptoms (internal bleeding) are delayed 3-5 days, so prompt testing even before signs appear is important.

My puppy keeps eating dirt outside. Is this normal?

In puppies under 6 months, occasional exploratory mouthing of soil is a normal developmental behavior. However, if a puppy is actively and repeatedly swallowing significant amounts of dirt rather than just sniffing and mouthing, it should be evaluated. Ensure the puppy is on a complete and balanced diet appropriate for growth, and is on a standard deworming schedule. Puppies are particularly susceptible to intestinal parasites acquired from soil, and geophagia increases their exposure risk significantly. A fecal test at the first puppy visit establishes whether parasites are already present.
