Consider dog’s size, coat, age when deciding on a sweater

Dear Cathy: When I walk my King Charles spaniel, I’ve noticed a lot of dog owners have their dogs bundled up with coats on. My dog has a beautiful thick coat and from all appearances isn’t bothered by the cold weather. She goes out into the backyard first thing every morning and spends 10 to 12 minutes checking out her territory.

Should she be wearing a coat of some sort? If not, how cold can dogs, and especially my dog Rosie, stand before needing some protection against low temps? — Tom, Jamesport, N.Y.

Dear Tom: What a great question. There is no general temperature rule for when dogs should wear winter coats, but when temperatures drop below 40 degrees, pet parents should consider a number of factors when deciding if their pet needs extra protection.

First, consider the dog’s size. Dogs less than 20 pounds and with shorter coats tend to get colder faster and may be shivering at 40 degrees, whereas a dog like Rosie with a heavy coat may love the brisk air. Other factors to consider include an individual dog’s tolerance for cold; a dog’s age (senior pets may need extra protection); and the length and thickness of a dog’s coat.

Each day also presents a new set of weather circumstances. For example, it could be 35 degrees outside but sunny, which may be easier for dogs to tolerate, than a 35-degree day that’s windy, wet and icy.

The best determinant, however, is how your dog actually behaves in cold weather. Many Cavalier spaniels have thick coats, and Rosie may be just fine without any outerwear on most days.

If Rosie balks about going or staying outside or starts shivering from the cold, then you might want to consider a coat. Otherwise, she sounds like she loves cold weather.
