TL;DR: Rat poison ingestion is a life-threatening emergency that requires immediate veterinary care, even if your dog appears normal, as symptoms can be delayed and damage may be irreversible.
What happens if my dog consumes rat poison?
Rat poison ingestion occurs when a dog consumes rodenticide pellets or blocks. These products are formulated to be highly palatable to pests, which unfortunately makes them attractive to pets as well. The most common types include anticoagulants that cause internal bleeding, neurotoxins that cause brain swelling, and vitamin D3-based toxins that lead to rapid kidney failure.
Is rat poison ingestion a veterinary emergency for my dog?
- Urgency Level: High. This is a life-threatening emergency; contact a veterinarian or a pet poison control hotline immediately.
- The toxic effects of rat poison are often delayed by hours or even days, so you must act even if your dog is currently acting normally.
- Waiting for symptoms to appear can be a fatal mistake, as internal damage is often irreversible by that point.
How does taking a photo of the rat poison packaging help my veterinarian?
- If you have access to the product packaging, take a clear photo of the active ingredients and the EPA registration number.
- Because there are several different classes of rodenticides, each requires a completely different treatment protocol.
- Providing a photo allows the veterinary team to prepare the correct antidote or decontamination procedure before you even arrive at the clinic.
Clinical Context (Merck Veterinary Manual)
In cases of suspected rodenticide ingestion in dogs, immediate steps are crucial. If within 4 hours of ingestion, induce emesis using 3% hydrogen peroxide or apomorphine. For bromethalin exposure, if the ingested dose in dogs is 0.1-0.49 mg/kg, emesis may suffice if successful. If emesis fails or more than 4 hours have passed, administer activated charcoal at 1-2 g/kg body weight, while being mindful of aspiration or hypernatremia risks. For zinc phosphide ingestion, emesis can be induced with apomorphine; gastric acid reduction via oral magnesium hydroxide antacid or famotidine (1 mg/kg, SC) may be beneficial. Consider activated charcoal, but avoid if vomiting persists due to aspiration risk. Obtain a baseline biochemical profile with repeat liver and renal value evaluations at 24, 48, and possibly 72 hours.
