Does my dog need a coat on?

If there’s snow and ice on the ground, or persistent chilly winds, then a winter jacket for your dog is a good idea. Small or thin-furred breeds, puppies, and senior dogs will generally need a winter coat when the temperature outside feels at or below 32°F (0°C).

A good rule of thumb, no matter what the breed, is that if your dog seems cold—shivering, whining, or slowing down—a coat can’t hurt.

There are lots of dogs that can benefit from wearing coats when it’s cold out, but for different reasons.

• Shorter-haired dogs: Dogs with fine hair, especially if they have low body-fat, will get cold faster. These include Greyhounds, Whippets, Pit Bulls, and Chihuahuas, among others.

• Small dogs and puppies: These little guys don’t generate or retain as much body heat as large dogs.

• Senior dogs: Older dogs have weaker immune systems and often suffer from arthritis or other age-related ailments; cold can exacerbate these problems.

• Dogs with medical conditions: Heart disease, kidney disease, and diabetes  can interfere with a dog’s ability to maintain body temperature.

• Short-legged dogs: Dogs like Basset Hounds, Dachshunds, and Corgis can lose heat quickly if their low stature puts them in contact with snow.
