Even though shedding is normal for nearly all types of dogs, sometimes your dogâ€™s hair loss can be a sign of a something more serious.
Hereâ€™s a look at why dogs shed, whatâ€™s considered a â€śnormalâ€ť amount of shedding, and the warning signs of a potential problem.
Reasons Why Dogs Shed Their Coats
A dogâ€™s fur helps control their body temperature and protects their skin against the sun and other environmental elements.
When a dogâ€™s hair stops growing, they will naturally lose it by shedding.
The amount and frequency of shedding will depend on several factors, including:
A dogâ€™s health condition
A dogâ€™s breed
Season and environment
Although dogs naturally shed, hair loss can also be caused by stress or health issues. Here are a few of the most common causes of shedding in dogs and what you should look out for.
Dogs, especially double-coated breeds, typically shed their undercoats during the spring and fall.
Heavy-shedding breeds include:
What might seem like heavy shedding can be completely normal for some dogs, but it can also be the result of an underlying health condition. If you notice excessive shedding, contact your veterinarian to set up an appointment.
If thereâ€™s been a big change in your dogâ€™s environment, the amount of hair they shed can increase. Dogs also tend to shed more when in stressful situations, like going to the vetâ€™s office.
If you think your dog may be experiencing stress- or anxiety-induced shedding, talk with your veterinarian. They can refer you to a qualified, board-certified veterinary behaviorist.
Certain skin disorders may also lead to hair loss and bald patches.
For example, an infestation of parasites, like fleas,?lice,?or?mites, can cause excessive hair loss.
Ringworm,?dermatitis,?and certain types of fungal infections, immune diseases, and cancers can cause hair loss, too.
If you notice skin irritations, like bumps, scabs, or a rash, in addition to hair loss, speak with your veterinarian immediately.
Allergies are another cause of shedding in dogs.?Certain foods, medications, household cleaners, and grooming supplies may trigger allergic reactions in dogs.
Allergies fall into four categories:
These allergies can result in hair loss or shedding. Your veterinarian can help pinpoint the offending allergen and find the most effective treatment.
What Is a Normal Amount of Shedding?
There is no â€śnormalâ€ť amount of shedding. There are so many variables that can change and affect the amount of shedding a dog does. The best way to find out if your dogâ€™s shedding is a sign of a health issue is to make a vet appointment and talk with them.
They will do a complete health check and diagnostics to rule out any potential health reasons that could be causing or contributing to your dogâ€™s shedding.
How Can I Manage My Dogâ€™s Shedding?
While you canâ€™t prevent a healthy dog from shedding normally, you can ask a groomer or veterinarian for product recommendations that will work with your dogâ€™s fur type and to help reduce the amount of shedding and loose hair in your home.
If you are concerned that your dog is experiencing hair loss due to a pest infestation, a skin condition, stress, or a medical issue, work with your veterinarian to pinpoint the issue and treat it appropriately.?
