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.
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.
