Watch out for glycol – it’s poisonous to dogs
Glycol, commonly found in antifreeze, is a household item that’s highly toxic to your dog. It’s vital to store any liquids containing glycol safely out of reach.
Glycol, or ethylene glycol as it’s technically known, is present in brake fluid, antifreeze, and screenwash. It has no smell but tastes sweet, which can tempt dogs to lick it up. Ingesting glycol is extremely dangerous for dogs; even a small amount can sadly be fatal, often leading to such severe poisoning that the dog may die. A dog can die from as little as 4-7ml of ethylene glycol per kilogram of body weight.
If a dog ingests glycol, it can cause acute symptoms like staggering, vomiting, weakness, and convulsions. Increased thirst and urination are other signs of kidney damage. A dog's general condition can deteriorate quickly; they might seem cold or intoxicated. Sometimes, their condition appears to improve initially, but this is often short-lived before worsening, with symptoms like an increased heart rate and breathing difficulties. You might also notice coughing, a forceful heartbeat, and severe convulsions that can lead to a coma.
Like many other poisonings, glycol poisoning symptoms can be similar to other conditions. If you suspect glycol poisoning, go straight to the vet for an examination and diagnosis. Glycol is absorbed rapidly by the body, so prompt treatment, including IV fluids, is crucial for recovery.
Always store liquids containing glycol where your dog cannot access them! Be careful and immediately clean up any accidental spills. Also, prevent your dog from licking the ground in areas with vehicles or potential glycol spills, such as car parks.
If you suspect or know your dog has ingested glycol, seek veterinary advice immediately. Call the vet clinic on your way so they can prepare for your arrival.
