Dogs have built-in fur coats, but they can still get dangerously cold when the temperature plunges in the winter. Chances are, Fido will still happily wait for walk-time and get excited when you reach for the leash, so it’s up to you to determine your dog’s tolerance for a romp in the snow. Here’s a handy infographic created by Dr. Kim Smyth, a staff veterinarian with pet insurance company Petplan, modeled after a scale developed by Tufts University that determines how canines respond to weather conditions depending on their builds.
Smaller dogs (Chihuahuas, Pugs), thin dogs (Whippets, Greyhounds) and senior dogs need the most protection from the biting cold and can benefit greatly from a winter coat. Even if your dog doesn’t need a winter coat, it certainly won’t hurt – as long as they don’t mind wearing one.
