Emergency

Antifreeze (ethylene glycol)

Applies to: Dog · Cat

Extremely toxic and sweet-tasting. Causes irreversible kidney failure if not treated fast.

Possible symptoms

Drunken behaviour, vomiting, increased thirst and urine, then no urine.

What to do

Emergency IMMEDIATELY. Minutes matter.

Why it is a problem

Antifreeze contains ethylene glycol, which tastes sweet and is extremely toxic. Even a small amount can cause severe kidney failure in dogs and cats, and early signs can look like drunkenness before they disappear, falsely suggesting recovery.

What a vet may do

This is an extreme emergency. Treatment must begin as early as possible, often within hours of ingestion, and may include an antidote and hospital care.

How to prevent it

Clean up spills at once, store products sealed and out of reach, and consider safer propylene-glycol-based products.
