Dog Ate Rat Poison?

Rat poison is a life-threatening emergency for dogs. Different types of poison require different treatments — bring the packaging to the vet if possible.

Emergency

Rat poison is a veterinary emergency — act now

All types of rat poison (rodenticide) are designed to kill mammals and are extremely dangerous to dogs. Symptoms may not appear for 1-5 days depending on the type, but by then, organ damage may already be severe. Immediate treatment dramatically improves survival.

Types of Rat Poison

🩸

Anticoagulants

Most common type. Prevents blood clotting. Symptoms (bleeding) may not appear for 2-5 days. Treatable with vitamin K.

🧠

Bromethalin

Causes brain swelling. Symptoms include tremors, seizures, and paralysis. No antidote — early decontamination is critical.

💊

Cholecalciferol (Vitamin D3)

Causes dangerously high calcium levels, leading to kidney failure. Requires aggressive IV fluid treatment.

Zinc/Aluminum Phosphide

Releases toxic gas in the stomach. Extremely dangerous. Requires immediate veterinary decontamination.

Common Questions

How long does it take for rat poison to affect a dog?
It depends on the type. Anticoagulant poisons may not show symptoms for 2-5 days. Bromethalin can cause neurological symptoms within 2-24 hours. Cholecalciferol may take 1-3 days. This delayed onset is why you shouldn't wait for symptoms — by then, significant damage may already be done.
Can a dog survive eating rat poison?
Yes, with prompt veterinary treatment, most dogs can survive rat poison ingestion. The prognosis depends on the type of poison, the amount ingested, and how quickly treatment begins. Anticoagulant poisoning has an excellent survival rate when treated with vitamin K. Other types may require more intensive care.
Can dogs get poisoned from eating a poisoned rat?
Yes — this is called secondary or relay poisoning. If a dog eats a rodent that has consumed rat poison, the dog can be exposed to the toxin. The risk is lower than direct ingestion but still real, especially with repeated exposure. If your dog regularly catches rodents in an area where poison is used, consult your vet.
