Antifreeze: a dangerous poison for dogs and cats
Updated : October 6, 2026
As the first cold arrives, antifreeze returns to garages and driveways. Many products contain ethylene glycol, a substance that is very toxic to animals, even in small amounts.
Why it is dangerous
Antifreeze can attract animals with its smell and sweet taste. Once swallowed, it can seriously damage the kidneys. Signs are not always immediate, which often delays care.
Possible signs
- Unsteady walking, as if drunk
- Vomiting, excessive thirst
- Lethargy, tremors
- Trouble standing
What to do
If you think your pet licked or swallowed antifreeze, call an open clinic immediately, even if it seems fine. Treatment works much better when started early. Bring the product container if possible.
Do not induce vomiting unless staff tell you to.
Prevention
- Store products out of reach, tightly closed
- Wipe up any spill right away
- Look for propylene glycol products, which are less toxic (still keep them out of reach)
- Watch your pet when walking near parking lots and garages
