Some dogs shed seasonally – typically during spring and fall, though in reality, most dogs shed all the time. Shedding is a normal behavior; it’s a natural way for a dog to get rid of old, dead hair and replace it with new hair growth. Depending on the type of coat your dog has, their pattern of shedding may vary. Excessive shedding that takes place outside of season could be due to a simple climate change or in some more rare cases it could be a sign of an underlying medical condition.

Types of dog coats that shed

Dogs have short hair, long hair, curly hair, flat hair, and single coats and double coats. Genetics has produced dog breeds with many different styles of coats that behave differently. Some breeds have hair that grows continuously and does not shed. Dogs with short, thinner hair don’t have the insulating undercoat. These breeds, like Chihuahuas, typically shed all year-round.

Some dogs, such as Afghan hounds, don’t shed, according to the AKC, but have such long hair that it needs to be brushed and groomed regularly. Regardless of whether your dog sheds regularly or not, all breeds can benefit from weekly brushing, which removes dead hair and keeps mats from forming.

Others have an outer longer layer of hair and a short, inner layer for insulation. Dogs with an insulating layer of hair are bred for cold climates – think Siberian huskies, Alaskan malamutes, and retrievers. These dogs often shed twice per year depending on the season (late spring and late fall). It’s probably not surprising that dogs with two layers of fur shed more often and in more copious amounts than dogs with only one layer.

Reasons for dog shedding

​Light and climate​

Since climate and temperature often trigger shedding in dogs, animals exposed to year-round artificial light (in other words, all of our indoor pets) may also shed all year round. Animals that live outside are exposed to seasonal changes in sunlight and temperature that trigger their seasonal shedding that indoor pets don’t get.

​Stress and Anxiety​

Stress is another factor that contributes to hair loss – it happens with people too. Severe stress causes many hairs to enter the resting phase all at once, causing them to fall out en masse rather than at different times. Depending on the sensitivity of your pet, this type of stress and anxiety can be caused by many different things. Moving to a new house or adding or losing a fellow pet friend can impact your dog. If stress and anxiety could be the cause, keep an eye out for other symptoms, like excessive chewing or licking, or destructive behavior.

​Medical Causes for Shedding​

Unusual shedding can be an indication of parasites, skin allergies, fungal or bacterial infections or contact with toxic substances. Excess shedding can be an indication of thyroid, kidney, or liver disease or an immune system disorder. It also can be a hormone imbalance. See your vet if your dog is losing hair in patches, which could be a sign of mange or ringworm, or if they have open sore spots or a severe skin irritation. Your vet will take a skin culture and conduct a physical exam to determine the underlying cause of the problem and treat it accordingly.

Other Solutions and Considerations

Some people decide to shave their dogs instead of waiting for hair to fall out, but this can have negative effects on a dog’s wellbeing. It may also fail to resolve the shedding problem, as dogs will still shed whatever shaved hairs remain in an attempt to keep to their biological programming. Shedding and growing new coats are essential to a dog’s temperature regulation and shaving your dog’s coat could make it difficult for your dog to adjust to changing climates. This is true for both summer and winter coats. Although it seems counterintuitive, a dog’s thick undercoat acts as protection from the sun and the heat as much as its winter coat acts as protection against the elements and the cold. Furthermore, once a dog has been shaved—especially double-coated dogs—the coat may never grow back the same.

In Conclusion

Hair growth is controlled by genetics, with some dog hair growing until it reaches a certain length. After the growth stage comes a resting stage, followed by a stage in which the hair dies and is ready to fall out to be replaced with new growth. For many dogs, this happens seasonally, in spring and fall. For others, it happens year-round. All dogs will shed at least a little all year long.

Some medical conditions can cause excessive shedding out of season. Look for changes in your dog that could indicate parasites (patchy loss of hair), allergies, or immune system or hormonal disorders. Regardless of the type of hair your dog has or its genetic disposition toward shedding, regular brushing cuts down on the amount of hair that drifts around your house or adheres itself to your furniture.

Shedding can be difficult to deal with, and at times it can feel like there aren’t enough lint-rollers in the world to keep up with the seasonal infestation of dog hair. Still, nature knows what’s best for your dog, and shedding is a part of that. Keep a dog brush close at hand, and while you are at it, don’t forget to clean the hair out with your own hairbrush!
