Why Is My Dog Shedding So Much? Here’s What You Need to Know

Shedding is a normal part of life for dogs. Their fur helps protect their skin, regulate their temperature, and insulate them from the elements. Like how we lose hair daily, dogs naturally shed too, though some breeds shed more than others—especially during seasonal changes.

But what if your dog seems to be shedding excessively? It might be a sign of something more serious. Understanding your dog’s normal shedding pattern can help you know when to take action.

What’s Considered Normal Shedding?

How much shedding is “normal” for a dog depends on several factors—breed, size, and even genetics. It’s a good idea to get familiar with your dog’s typical shedding pattern as soon as you bring them home.

Contrary to popular belief, long-haired dogs don’t always shed more. In fact, short-haired breeds often have denser coats and shed more frequently, but because their hair is shorter, it’s less noticeable.

Some breeds, like Labrador Retrievers, are known to be heavy shedders. As Dr. Roy Cruzen, a veterinarian in Phoenix, explains, “Labs are like shedding machines. They can leave a trail of hair in just a 20-minute visit to the vet!” Other heavy-shedding breeds include Akitas, Chow Chows, Dalmatians, German Shepherds, and Siberian Huskies.

Causes of Excessive Shedding

If your dog’s shedding seems more intense than usual, there could be several reasons behind it. Here’s what to watch for:

1. Seasonal Shedding

Dogs with double coats often shed more during seasonal transitions. When it gets warmer in spring, they shed their thick winter coat for a lighter summer one. The reverse happens in the fall when they grow a thicker coat to prepare for winter.

2. Poor Diet

One of the top reasons for excessive shedding is an imbalanced diet. Low-quality dog food may lack the necessary nutrients to support healthy skin and fur. Dr. Cruzen explains that buying cheaper food from discount stores can lead to more shedding because it might not provide enough protein or essential nutrients. Always opt for high-quality food that meets the nutritional standards of the Association of American Feed Control Officials (AAFCO) and ask your vet for recommendations.

3. Food Allergies or Intolerances

Allergies, whether from food or the environment, can cause excessive shedding, itchy skin, and even bald patches. If your dog’s shedding seems to come with itching or skin infections, it’s worth talking to your vet. Environmental allergies like pollen or grass could also be to blame.

4. Wrong Shampoo

If diet and allergies aren’t the issue, it could be your grooming routine. Human shampoos are too harsh for dogs and can cause irritation, excessive shedding, or even skin infections. Stick to dog-safe shampoos and make sure to rinse thoroughly to avoid buildup that can irritate the skin.

5. Stress

Dogs shed more when stressed—whether it’s a change in routine, new family members, loud noises like fireworks, or even a visit to the vet. The stress hormone adrenaline (also called epinephrine) is thought to play a role in this.

6. Parasites

Fleas, ticks, and mange mites can lead to excessive shedding and constant scratching. These parasites can cause serious skin problems if left untreated, including infections. Make sure your dog is on a year-round flea and tick preventative to keep them safe.

7. Hormonal Imbalances or Health Issues

Excessive shedding can also be a sign of deeper health problems like hormonal imbalances, which can occur after spaying or neutering, or as a result of thyroid disease or Cushing’s disease. Clumps of shedding or bald spots may also point to bacterial or fungal infections, like ringworm. If you notice these signs, it’s time to visit the vet.

When to See the Vet

If your dog’s shedding seems extreme—especially outside of peak shedding seasons—it’s a good idea to check in with your vet. Keep an eye out for additional symptoms, such as:

• Bald spots
• Dull, flaky skin
• Increased thirst or urination
• Weight changes
• Visible parasites
• Excessive scratching or itching

If you notice any of these along with heavy shedding, your dog might need a professional checkup to rule out underlying issues.

FAQs About Dog Shedding

When should I worry about my dog’s shedding?
If your dog is shedding heavily along with other symptoms like hair loss, itchy skin, or changes in behavior, it’s time to visit the vet.

When do dogs shed the most?
Dogs typically shed the most in early spring and early fall, especially those with double coats.

How can I reduce my dog’s shedding?
You can’t stop shedding entirely, but you can reduce it with regular grooming. Brushing your dog with a slicker brush or grooming mitt can help remove loose hairs before they end up all over your home.

Shedding is normal, but knowing your dog’s typical shedding patterns will help you catch any changes that might signal a health issue. And with a little extra care, you can keep your dog’s coat healthy and your home a little less hairy!
