Signs Your Pet May Have Food Poisoning: What to Watch For and When to Act

Pet food poisoning can range from mild GI upset to a life-threatening emergency. Knowing the difference can save your pet's life.

General Signs of Food Poisoning: Gastrointestinal

VomitingSingle episodes are common and not necessarily alarming. Repeated vomiting (more than 2–3 times in a few hours), vomiting that continues into the next day, or vomiting containing blood is cause for concern.

DiarrheaLoose stool or liquid diarrhea, especially if persistent, watery, or bloody.

Bloody stoolBright red blood (hematochezia) indicates lower GI bleeding. Dark, tarry, or black stool (melena) indicates upper GI bleeding. Either is serious.

Excessive droolingCan indicate nausea, throat irritation, or toxin ingestion.

Loss of appetiteRefusing to eat is a general sign that something is wrong. In cats especially, more than 24 hours without eating warrants a vet call.

Abdominal painSigns include hunching, reluctance to move, whimpering when the abdomen is touched, or unusual restlessness.

General Signs: Systemic

Lethargy & weaknessSignificantly less active, responsive, or playful than usual.

FeverDogs' normal temp: 101–102.5°F; cats' normal: 100.5–102.5°F. Above 103.5°F in either species warrants a vet call.

DehydrationSunken eyes, dry or tacky gums, slow skin tenting, and reduced urination.

Pale/white/gray gumsGums should be pink and moist. Pale or white gums indicate poor circulation — this is a serious emergency.

JaundiceYellow-tinged eyes, skin, or gums indicate liver involvement. Particularly associated with aflatoxin poisoning. This is an emergency.

Symptoms by Contamination Type

Salmonella (12–72 hrs after ingestion)

Sudden onset vomiting/diarrhea (often watery and foul-smelling), fever, lethargy, possible blood in stool. High human transmission risk — wash hands thoroughly.

Aflatoxin (Days to weeks to appear)

Lethargy (often first sign), loss of appetite, vomiting, jaundice, unexplained bruising, dark urine. By the time jaundice is visible, liver damage is already severe. Don't wait — see a vet immediately.

Vitamin D Toxicosis (Days to weeks of exposure)

Excessive thirst, excessive urination, loss of appetite, vomiting, drooling, weakness, weight loss.

Listeria (1–4 weeks after exposure)

Fever, vomiting, diarrhea, muscle stiffness, loss of coordination. High human transmission risk, especially for pregnant women and immunocompromised individuals.

Pentobarbital (Rapid onset)

Extreme sedation, loss of coordination, difficulty breathing, unconsciousness, death. IMMEDIATE EMERGENCY — go to an emergency vet now. Do not wait.

Foreign Material (Variable)

Sudden reluctance to eat, pawing at mouth, gagging, bloody stool, abdominal pain.

Withhold food 12–24 hours to rest the stomach (not for puppies or diabetic dogs)

After fasting: bland diet of plain white rice + boiled chicken (no seasoning)
Continue bland diet 2–3 days, then gradually reintroduce normal food
