Do Dogs Need Jackets? Here’s What Pet Experts Really Say

As the temperatures drop, dog parents may wonder whether their dogs need winter coats to stay safe and warm during the frigid season. Not all dogs need a winter coat, and in some cases, the extra layer of warmth can actually do more harm than good. However, under the right conditions, most dogs can benefit from an additional layer of protection from the elements.

Find out below when it’s safe, and necessary, to put a winter coat on your dog.

Why Do People Buy Jackets for Their Dogs?

Sometimes, the decision to put a jacket on a dog is purely emotional. Walking your dog in frigid temperatures can be emotionally distressing because you are concerned for your dog. Since most dogs require time outside to go to the bathroom and release excess energy, it’s no surprise that dog owners would take a rather safe-than-sorry approach.

Should My Dog Wear a Jacket?

Many factors come into play when determining whether or not you should put a jacket on your dog. It’s important to take into account windchill, whether or not your dog could get wet, and how sunny it is before taking your dog outside. When in doubt, play it safe. You can always take the coat off if your dog appears to be getting too warm. Any time you’re out in the cold and see your dog shivering, seeking out warmth, limping, slowing down, or acting anxious or distressed in any way, it’s time to go inside.

A dog’s age, health status, and acclimation to cold temperatures should also be considered. Elderly dogs, puppies, and sick dogs can have trouble staying warm even under mild conditions, while a healthy adult dog who is used to the cold can be quite happy even when it’s very chilly.

Which Dog Breeds Need a Jacket?

Small dogs have relatively more surface area through which to lose heat than big dogs, so all other things being equal, smaller dogs benefit from jackets at higher temperatures than bigger dogs. A few breeds that fit this group are Chihuahuas, toy terriers, and Miniature Pinschers. Body fat helps hold the heat in, so a thin dog, like a Whippet or Greyhound, will often appreciate a coat more than an overweight dog. Dogs with very thin fur can get cold quite easily, so they are typically good contenders for a jacket.

On the other hand, large dogs with long or thick hair that have their own thick double coats rarely require a jacket. In fact, its weight can actually reduce the natural insulating properties of the dog’s fur. Dark fur also absorbs more heat from the sun than light fur. Activity generates a lot of heat, so any dog will be warmer when they are running around versus sitting quietly. The following dogs rarely (if ever) should wear a jacket because of their size and long or dense fur:

• Huskies
• Newfoundlands
• Chow Chows
• Pomeranins
• Komondors
• Havanese
• Bernese mountain dog
• Bearded collie
• Great Pyrenees

Before ultimately deciding to (or not to) put a jacket on your dog, ask your vet for advice specific to your pup.

How to Shop for a Dog Jacket

Once you have determined that your dog could use a jacket—and got approval from your vet—you can start shopping around.

First, consider the type of material your dog’s coat should be made of. Ask your vet for recommendations on materials that are compatible with your dog’s fur coat type and your location’s weather conditions.

Also, consider measuring your dog before buying them a jacket, since sizing is dependent on your particular dog. Use a soft tape measure to record your dog’s measurements, which will help to ensure the jacket will fit when it arrives. You want to be sure that the coat you choose isn’t too tight, loose enough to drag on the ground or fall off your dog, or prevents your dog from moving normally.
