As temperatures shift, many dogs begin their seasonal coat change, releasing tufts of fur in a whirlwind of shedding known as "blowing coat." For dog owners, this period can feel like an endless battle against drifting hair—but understanding the process makes it more manageable. Here's what you need to know about why dogs blow their coats and how to handle it without losing your sanity (or your vacuum).

What Does It Mean When a Dog Blows Their Coat?

"Blowing coat" refers to the intense shedding that occurs in some dog breeds, especially those with double coats. A double coat consists of a dense, soft undercoat that provides insulation and a tougher outer coat that offers protection from the elements. When the seasons change—typically spring and fall—dogs shed their undercoat to adapt to the upcoming weather.

This shedding is part of a natural hair growth cycle involving four stages:

  • Anagen: New hair growth begins.

  • Catagen: Growth slows as the hair reaches full length.

  • Telogen: The hair becomes dormant but remains attached.

  • Exogen: Old hair falls out to make room for new growth.

When dogs blow their coat, they're transitioning through the exogen phase on a large scale. The result is handfuls, if not piles, of loose fur tumbling off your dog and onto your floors, furniture, and clothes.

How Often Do Dogs Blow Their Coat?

For double-coated breeds, this usually happens twice a year—once in the spring to get rid of the thick winter coat, and again in the fall to shed the lighter summer layer and prepare for colder weather. Indoor dogs might shed year-round due to constant exposure to artificial light and stable temperatures, but the heaviest shedding often aligns with seasonal changes.

The coat-blowing process typically lasts between two and four weeks, depending on the breed and individual dog. If your dog seems to be shedding excessively outside of these windows or displays skin issues, consult your vet.

Breeds Known for Blowing Their Coats

Some breeds are particularly notorious for their coat-blowing habits. These include:

  • Siberian Husky

  • Alaskan Malamute

  • German Shepherd

  • Golden Retriever

  • Saint Bernard

  • Akita

  • Great Pyrenees

  • Chow Chow

  • Labrador Retriever

  • Australian Shepherd

  • Shiba Inu

  • Newfoundland

  • Cardigan and Pembroke Welsh Corgis

Whether large or small, many northern breeds or dogs with thick double coats fall into this category. The common factor is their insulation-rich fur, which responds dramatically to temperature changes.

How to Manage Coat Blowing at Home

Shedding season can be intense, but a few simple tools and strategies can make a big difference.

  1. Brush Daily—Sometimes Twice: Use an undercoat rake or de-shedding tool designed for double-coated dogs. Brushing daily (or more frequently during peak shedding) helps remove loose hair before it ends up around your home.

  2. Give Regular Baths: A warm bath with a deshedding shampoo can loosen dead hairs. Follow with a thorough drying and brushing session to maximize hair removal.

  3. Upgrade Your Cleaning Tools: Invest in a powerful vacuum made for pet hair, lint rollers, and washable furniture covers. Clean your dog’s bed frequently to reduce fur buildup.

  4. Mind the Airflow: Fans, air vents, and open windows can blow loose fur around the house. Keeping air movement controlled can help you track where hair tends to collect.

  5. Protect Your Wardrobe: Dark clothing and fur don’t mix. Put away lint-prone garments or wear pet-friendly fabrics during heavy shedding periods.

  6. Don’t Shave Double-Coated Dogs: Tempting as it may be, shaving a double-coated dog interferes with their natural insulation and protection. It can even lead to skin problems or permanent damage to the coat’s texture.

  7. Visit a Groomer If Needed: If the shedding feels overwhelming, a visit to a professional groomer can help manage the bulk of the blowout.

When Shedding Isn’t Normal

Blowing coat is a healthy, natural process—but if your dog’s shedding seems excessive or is paired with symptoms like itching, redness, bald patches, or changes in behavior, consult your vet. These may be signs of allergies, nutritional deficiencies, or underlying skin conditions.

Final Thoughts: Stay Calm and Keep Brushing

Blowing coat season is a natural part of life with many dog breeds. It may be messy, but it doesn’t have to be miserable. With the right tools, a consistent grooming schedule, and some patience, you can manage the shedding and keep your home—and your dog—clean and comfortable.

Understanding what’s happening during shedding season is half the battle. The other half is staying proactive and turning brushing into a bonding moment with your furry friend. Before long, the fluff will settle—and so will your nerves.
