As winter weather settles into Whatcom County, veterinarians are warning pet owners to be alert to seasonal hazards that can be dangerous — and in some cases deadly — to cats and dogs.

Antifreeze, ice melt products and road salt are among the most common winter toxins affecting pets, according to Whatcom Veterinary Hospital. Even small amounts of antifreeze can be fatal if ingested. The liquid has a sweet taste that can attract animals, and leaks often go unnoticed in garages, driveways and sidewalks.

“The most effective way to protect your pets against these winter toxins is to reduce and prevent the possibility of exposure. If your pet does have contact with a toxic substance do not wait until they start showing symptoms, contact animal poison control immediately to determine the level of risk your pet is facing, followed by a call to your regular veterinary office for follow up care. Do not wait and see with toxic substances like antifreeze, once the symptoms show, it is usually too late to help save your pet.”

Road salt and ice melt products can also cause problems. Chemicals used to melt ice may irritate paws, leading to cracking, burning or infection. Pets can also become sick after licking their paws to clean them. Veterinarians recommend wiping paws after walks, limiting exposure to treated surfaces and using pet-safe ice melt when possible.

Owners are encouraged to store antifreeze securely, clean spills promptly, monitor pets closely outdoors and watch for signs of distress such as vomiting, drooling, weakness, paw discomfort or sudden lethargy.

Whatcom Veterinary Hospital urges pet owners to contact a veterinarian right away if an animal may have been exposed to a winter toxin, noting that quick action can make a lifesaving difference.
