Dog Coats: When Dogs Need Them (and When They Don’t)

As temperatures change, many dog owners wonder: Does my dog really need a coat? The answer depends on your dog’s coat type, size, age, health, and the weather conditions. Not all dogs are built the same, and understanding your dog’s natural insulation helps you make the best choice for their comfort and safety.

Why a Dog’s Coat Matters

A dog’s natural coat plays a crucial role in:

• Regulating body temperature

• Protecting skin from wind, moisture, and sun

• Providing insulation in cold weather

Some dogs are naturally well-equipped for colder temperatures, while others lack the insulation needed to stay warm — especially in wind, rain, or freezing conditions.

Coat Types & Cold Tolerance

Double-Coated Breeds

Examples: Golden Retrievers, Labradors, German Shepherds, Huskies

These dogs have an insulating undercoat with a protective outer layer. They generally tolerate cold better than other breeds.

May need a coat when:

• Temperatures drop below 32°F (0°C)

• It’s wet, windy, or icy

• They are seniors, puppies, or have medical conditions

A waterproof or wind-blocking coat can be helpful even for double-coated dogs in harsh conditions.

Single-Coated or Low-Insulation Breeds

Examples: Greyhounds, Whippets, Boxers, Dobermans

These dogs lack an insulating undercoat and lose body heat quickly.

Should wear a coat when:

• Temperatures drop below 50°F (10°C)

• Wind chill or rain is present

• Walks last longer than a quick potty break

Insulated coats with chest and belly coverage are especially important.

Short-Legged or Small Breeds

Examples: Dachshunds, Chihuahuas, Toy breeds

Smaller dogs lose heat faster, and short-legged breeds are closer to cold ground.

Should wear a coat when:

• Temperatures fall below 45–50°F (7–10°C)

• Snow, frost, or cold pavement is present

Sweaters may work for mild cold, but insulated coats are best in winter weather.

Thin-Haired or Hairless Breeds

Examples: Chinese Crested, Xoloitzcuintli

These dogs have little to no natural insulation.

Should wear a coat when:

• Temperatures drop below 60°F (15°C)

• Anytime it’s cold, windy, or wet

Layered clothing or fleece-lined coats are often necessary.

Senior Dogs, Puppies & Dogs with Medical Conditions

Regardless of breed or coat type, dogs that are:

• Elderly

• Very young

• Arthritic

• Immunocompromised

• Underweight

may need coats at higher temperatures than healthy adult dogs.

Temperature Guidelines (General Rule of Thumb)

• 60°F+ (15°C+): Most dogs are comfortable without a coat

• 45–59°F (7–15°C): Coats recommended for small, thin-coated, or senior dogs

• 32–45°F (0–7°C): Many dogs benefit from a coat

• Below 32°F (0°C): Most dogs — even double-coated breeds — may need protection depending on exposure time and conditions

Signs Your Dog Is Cold

Watch for:

• Shivering

• Lifting paws

• Seeking shelter

• Slowing down or refusing to walk

• Tucked tail or hunched posture

If you’re cold, there’s a good chance your dog is too.

Choosing the Right Coat

Look for:

• Proper fit without restricting movement

• Coverage of the chest and belly

• Waterproof or windproof materials

• Easy on/off design

Avoid coats that mat fur or trap moisture.

Final Thoughts

Dog coats aren’t about fashion — they’re about comfort, safety, and well-being. Knowing your dog’s coat type and individual needs helps you make informed choices as the weather changes.

If you’re ever unsure, your groomer or veterinarian can help guide you.
