Dog Poisoning Symptoms: What to Do When Every Minute Counts

Keep the packaging or a photo of what was ingested. The specific substance, amount consumed, and your dog's weight determine the treatment protocol.

Do NOT induce vomiting unless specifically instructed by a veterinarian. For some substances (corrosives, sharp objects, petroleum products), vomiting causes additional damage.

Chocolate: Theobromine is the toxic compound. Dark chocolate and baking chocolate are the most dangerous. Milk chocolate is less concentrated but still toxic in large amounts. Symptoms appear 6 to 12 hours after ingestion: vomiting, diarrhea, rapid heart rate, tremors, seizures.

Xylitol (birch sugar): Found in sugar-free gum, candy, peanut butter, and baked goods. Extremely toxic to dogs. Can cause life-threatening hypoglycemia (low blood sugar) within 30 to 60 minutes and liver failure within 24 to 72 hours. This is an emergency even in small amounts.

Grapes and raisins: The toxic mechanism is still not fully understood, but even small amounts can cause acute kidney failure in some dogs. Not all dogs are equally susceptible, but there is no way to predict which dogs will react. Any ingestion should be treated as potentially serious.

NSAIDs (ibuprofen, naproxen): Common human painkillers that are toxic to dogs. Cause gastric ulceration, kidney damage, and in severe cases, kidney failure. A single ibuprofen tablet can be dangerous for a small dog.

Rat poison (rodenticides): Multiple types with different mechanisms. Anticoagulant rodenticides prevent blood clotting (symptoms may not appear for 3 to 5 days). Bromethalin causes brain swelling. Cholecalciferol causes kidney failure through calcium toxicity. The type matters for treatment, so bring the packaging.

2 to 6 hours: Absorption is increasing. Blood work can assess organ impact. IV fluids may be started to support kidney function.

6 to 24 hours: Symptoms typically manifest. Treatment becomes organ-supportive rather than decontamination-focused.

24 to 72 hours: For slow-acting toxins (anticoagulant rodenticides, xylitol liver damage, grape/raisin kidney damage), this is when the full impact becomes apparent.

Omelo's longitudinal health record ensures your vet has your dog's complete health baseline, including current medications and any pre-existing conditions that affect treatment decisions. In poisoning cases, this information can change the treatment protocol.
