Is antifreeze dangerous to dogs?
Antifreeze can be extremely dangerous to dogs. It can damage their kidneys and can cause death, even after only a small amount has been licked. Effects from poisoning can sometimes be seen quickly, but it’s often not until two to three days later that signs of kidney failure start to show.
Some types of antifreeze are more dangerous than others. The most toxic kind contains ethylene glycol, but some contain methanol or propylene glycol, which may not be as toxic but can still make your dog unwell.
How are dogs poisoned by antifreeze?
Dogs will most often come across antifreeze after it’s leaked from a car radiator, or been spilt after refilling screen wash. If you notice any liquids by your car, keep your dog away and clean it up immediately. If they’ve walked through any, then wash their paws with soap and water straight away. If you think your dog has licked, drank or been in contact with antifreeze, contact your vet immediately. The quicker your dog is treated the better.

- Radiator coolants
- Windscreen de-icers
- Brake fluids
- Developing solutions for photography
- Some paints, solvents and printer inks
- Rust inhibitors
- Some antifreeze treatments for ponds
- Some snow globes

Soon after drinking antifreeze, some dogs may be wobbly on their feet, may dribble or be sick.
