Is Your Dog's Shedding Normal? Vets Say This Common Symptom Could Signal Allergies

Every aspect of canine health is important, including dog coat health. In fact, a dog's skin and fur can be a fascinating sneak peek into their overall health if you know what to look for.

Although most dogs shed (especially dogs with long fur), some hair loss can seem excessive. If you've ever wondered, "Why is my dog shedding so much?" you're not alone. Keep on reading to learn when a dog's shedding is normal and what it may be trying to tell you.

How to Tell If Dog Shedding Is Normal

Some dogs shed twice a year, in the spring and summer, while others shed annually. Even though fur loss and thinning are normal during shedding season, unusual shedding can raise red flags. Dr. Tanya Leslie, Veterinary Advisor for Douxo, reveals a few telltale hints that shedding has become a bigger problem.

"Many pet parents assume that all shedding is just part of the season, but it's important to observe your dog's coat and skin carefully. Normal molting is usually even, while patchy hair loss, redness, scabs, or persistent greasiness and dandruff could be signs of an underlying skin condition or allergy."

A number of conditions can cause abnormal shedding in dogs, including:

• physical irritation
• infection
• allergy
• yeast overgrowth
• hormone disorder
• metabolic conditions

Checking a dog for other abnormalities can help narrow down the cause of excessive shedding. For example, the presence of dandruff, itchiness, and greasy or oily fur could suggest yeast overgrowth or an imbalance in the skin lipids, while increased thirst or sudden weight loss could point to a metabolic concern.

What to Do About Excess Shedding

As Dr. Leslie explains, prevention and awareness are key to dog coat health. Staying on top of grooming, bathing, and parasite treatments is essential for a thick, shiny coat, but these hygiene habits also promote overall wellness. Even brushing and bathing with the right products can make a major difference.

"Keeping their coat and skin clean helps prevent the build-up of dirt and debris that can cause discomfort," says Dr. Leslie. "Using gentle, dog-friendly skincare products can also support and strengthen the skin barrier, promoting overall skin health."
