Why Dogs Shed and What Influences It
This publication explains that shedding is a natural process in nearly all dogs — the body’s way of removing dead hair to make room for new growth and to adapt to seasonal temperature changes. There is no such thing as a truly non-shedding dog unless the breed is completely hairless. The degree of shedding varies widely between breeds and is determined by the hair growth cycle (anagen, catagen and telogen), along with genetics, nutrition and environmental factors. Coat type also matters: dogs with undercoats, double-coated breeds, wire-haired coats or long hair all shed differently. While many owners assume longhaired breeds shed more, it is often heavy undercoats — such as in Huskies, Malamutes, Pyrenean Mountain Dogs and Spitz breeds — that create the most noticeable shedding. Seasonal shedding also plays a major role, with many breeds losing large amounts of their winter coat in spring.
Shedding is influenced by sunlight exposure, temperature, hormones, pregnancy, nursing, allergies, parasites and overall health. Dogs with skin infections, flea or tick infestations, Cushing’s disease or autoimmune skin disorders may shed excessively. Nutrition is another key factor: essential vitamins, minerals, amino acids and fatty acids contribute significantly to skin and coat condition. Poor diet or deficiencies can increase shedding, while good grooming habits — such as daily brushing and using appropriate dog-specific shampoos — help reduce loose hair around the home. Regular deworming and proper management of allergies further support healthier skin and a more stable shedding pattern.
Managing Excessive Shedding and Supporting Coat Health
When a dog sheds excessively, the first step is to rule out underlying medical issues and ensure proper coat care. Daily brushing, especially during heavy shedding seasons, can dramatically reduce loose hair throughout the home. Feeding a high-quality diet and supplementing with nutrients that support skin and coat health — including omega-6 and omega-3 fatty acids, essential amino acids, minerals and vitamins — is strongly recommended. Because nutrients in liquid form are often absorbed more efficiently, the publication highlights complete nutritional formulas as an effective way to support skin and coat quality. Certain breeds naturally shed very little and are considered hypoallergenic, while others are heavy seasonal shedders; understanding a dog’s breed characteristics helps set realistic expectations for coat management.
Consistency in grooming, nutrition and parasite control remains the best strategy to maintain a healthy coat and reduce unwanted shedding.
