Dogs, like most animals, are not an exception to shedding. It is their bodies’ way of getting rid of all that excess fur. Yet, some dogs shed too much compared to others. Well, think about it. How often do dogs shed anyway? To answer that question, check out this article.

How Often Do Dogs Shed in a Year?

Dr. Laurel Davis from SunVet Animal Wellness said that dogs’ shedding season is normal. She added that hypoallergenic dogs shed less compared to double-coated dog breeds.

The Dog Advisory Council claimed that canines have an estimated 600-60000 hairs per square inch of their bodies. Meanwhile, zoologist Johnson Michaels stated that typical dogs lose 5 to 30% of hair daily.

Moreover, Dr. Marty Becker and Gina Spadafori from the Niles Animal Hospital said that canines are shed by season. They added that dogs shed twice a year.

Also, Adrienne Farricelli, a certified dog trainer, supports that claim. She explained that most dogs shed during the spring and fall. That is around March to May and September to November.

Yet, according to FourPaws, the spring and fall shedding season is for outdoor dogs only. Whereas indoor dogs shed their fur all year long.

Why Do Dogs Shed?

Normally, dogs often shed their undercoats. Yet, sometimes excessive shedding could have underlying problems. Let’s look at the reasons below.

Natural Hair Cycle

When dogs shed their coats, they also undergo a natural hair cycle like humans.  

  •  Anagen Stage. New hair grows. Breeds like Shih Tzu stay longer in this stage.
  • Catagen Stage. Hair stops growing.  
  • Telogen Stage. Hair becomes dormant but doesn’t shed.
  •  Exogen Stage. Old hair is shed.

Hypothyroidism

Carolina Veterinary Specialists said that hypothyroidism has two forms. They are idiopathic thyroid gland atrophy and lymphocytic thyroiditis.

Animal Hospital of Montgomery stated that shedding is a sign of Hypothyroidism. That also includes weight gain and lethargy. Further, this disease is common in middle-aged, medium to large dog breeds.

Congenital Problems

A study in 2006 stated that dogs could also suffer from congenital alopecia. Further, this disease causes dogs to shed, often resulting in bald spots.

Moreover, MSD Veterinary Manual suggested that alopecia may not be congenital.  Also, it was stated that the lack of hair follicles causes balding.

Allergies

According to Randy Kidd, DVM, dogs are not an exception to seasonal allergies. He added that allergies cause an estimated 70% of skin-related diseases in dogs.

Dogs are more prone to atopic dermatitis. Allergens in flea bites, pollens, dust, and cleaning products trigger intense shedding.

Diet

Malcolm Weir and Robin Downing, both DVM, explained that dogs fed with commercial dry food are prone to fur shedding.

Further, the Journal of Nutrition in 1998 stated that protein deficiency in dogs leads to brittle hair and shedding. Also, canine vitamin A deficiency can cause hyperkeratinization and alopecia.

Breeds That Shed a Lot

To understand the dogs’ shedding season, Dr. Davis explained the difference between dog fur and dog hair.

Also, according to her, hair is the topcoat while fur is the undercoat. Fur grows and sheds faster. Whereas dog hair grows slower and is longer. Thus, it doesn’t shed that much.

Pete Decker from Goody Pet listed the dog breeds that shed the most during the months of spring and fall.

  •  Alaskan Malamute
  •  Chow Chow
  •  German Shepherd
  •  Saint Bernard
  • The Great Pyrenees
  •  Golden Retriever
  •  Akita
  •  Belgian Tervuren
  •  Pomeranian
  • Belgian Sheepdog

The Peoria Area Veterinary Group said that double coats in dogs could be the reason why they are heavy shedders. They added that these dogs have dense undercoats and long topcoats.

Dogs shed their undercoats during temperature changes. For instance, canines will shed to cool themselves during the summer. Also, dogs shed to create dense undercoats for winter.

Breeds That Shed Less

There is no such thing as dogs that don’t shed. Yet, the shedding can be kept to a minimum. Also, Amy Flowers, DVM, explained that the amount of shedding depends on the breed of the dog.

Jenna Stregowski, RVT said that non-shedding dog breeds are only a myth. She added that all dogs shed but some are not noticeable.

According to Reader’s Digest, here are the lists of dog breeds that shed less during the year.

  • American Hairless Terrier
  • Basenji
  • Bedlington terrier
  • Brussels griffon
  • Chinese crested
  • Havanese
  • Maltese
  • Peruvian Inca Orchid
  • Poodle
  • Scottish terrier

Dogs come with two types of coats, the single-coated and the double-coated. Single-coated dogs shed less because they don’t have thick undercoats.

According to Dr. Farricelli, the hairs of single-coated dogs vary in length and texture. Also, she added that these dogs don’t shed by season but rather in small amounts annually.

How to Limit Coat Shedding

As dog owners, it can be tiring to clean up dog furs and hair all over the house. So, here are some tips on how to minimize coat shedding. 

Choose the Right Brush

Most dogs often shed their coats twice a year and when they do, they need regular brushing. Barbara Bird, a pet groomer from Arizona, stated that groomers use the same brush as dog owners do. Also, some of these combing tools include wide-toothed combs or bristle brushes.

Feed Your Dog a Healthy Diet

According to Volhard Dog Nutrition, an imbalanced diet causes shedding. They added that dry food lacks protein which leads to excessive shedding.  

Also, Dr. Jennifer Coates said that Lipids are important. For instance, omega 3 and omega 6 help maintain healthy skin and fur.

Bathe Your Dog Regularly

Regular baths are good for a dog’s overall health condition. It gets rid of fleas, detangles hair, and cleanses their skin of dirt and oil. 

Further, Vetgen Pharmaceuticals supports the idea of grooming. According to them, a dog’s routines should include, bathing, drying, and, then brushing.
