When Does Your Pet Actually Need an Outdoor Coat?

Just like people, pets need to regulate their body temperature based on the weather. But since a breed's size and coat length hugely affect how well it handles cold, putting a coat on every pet regardless of type isn't the right answer. You need to weigh temperature alongside your pet's build and coat condition to make an accurate call.

Small breeds and short-haired dogs have less body fat and lose heat fast, so a coat makes a real difference in cold weather. Large breeds and long-haired dogs — especially double-coated breeds — insulate themselves well and can usually handle moderate cold without one. Forcing a coat onto these breeds can actually make them uncomfortable or flatten their fur, reducing its natural insulating effect.

On very cold days below 41°F, putting a coat on puppies, senior dogs, or pets with health conditions is the safer call regardless of size or coat length. In hot weather, a coat can interfere with your pet's temperature regulation, so skip it unless strong sun exposure is a concern. Checking both the temperature and your pet's traits before a walk helps you keep them comfortable and healthy.

Frequently Asked Questions

Does every dog need a coat?

No. Large breeds and long-haired breeds usually insulate themselves well enough to handle cold without a coat. Small and short-haired breeds struggle more to hold onto body heat, so a coat helps them.

Should I put a coat on my pet in summer?

Generally no — a coat can interfere with temperature regulation in hot weather. A thin, breathable coat is an exception if you need sun protection.
