Is rat poison harmful to dogs?
Rat and mouse poisons, also known as rodenticides, are products formulated to kill rodents. The chemicals used in these products are often highly toxic to dogs and can cause internal bleeding, kidney failure, organ damage and even death if eaten by your dog.
Worryingly, many modern rodenticides have a palatable flavour in order to attract animals and could look like a tasty snack to your pup.
What would rat poison do to a dog?
There are several different types of rat poison and they act differently depending on the poisonous ingredient they contain. The most common type in the UK are anticoagulant rodenticides which prevent the blood from clotting, leading to internal bleeding.
Other varieties include cholecalciferol (vitamin D3) which ultimately causes severe, acute kidney failure, bromethalin which works to cause brain swelling and zinc and aluminium phosphides which release phosphine gas once in the stomach.
There are also a number of increasingly popular rodent poisons on the market containing the substance alphachloralose. This works by depressing the central nervous
system and treatment is very different to poisoning by anticoagulant rodenticides.
What to do if a dog eats rat poison?
If you suspect your dog has swallowed rodenticide call your vet or, out of hours, your nearest pet emergency service immediately. Rat poisoning in dogs is an emergency that can’t wait until morning.
Your vet will want to know as much information as possible in order to identify the type of poison and decide on the best course of treatment. If you can, take note of the following information to tell the vet:
- Your dog’s weight
- The day and time of exposure
- Brand name and manufacturer
- Active ingredients and their concentration
- Package size
- Approximately how much is missing from the pack
- Take the packaging with you if possible
