Dog Hair Loss: Why It Happens and What You Can Do About It

Losing hair is a normal occurrence for both humans and animals. For humans, it usually happens as we age and our hair follicles get smaller. For dogs, there are a number of reasons why they might lose their hair, including poor nutrition, parasites, allergies, and more. In this blog post, we will discuss the most common causes of dog hair loss and what you can do to help your furry friend!

Signs of Hair Loss in Dogs

The first thing to look for when determining if your dog is experiencing hair loss is the type of fur that’s falling out. If it’s thinning, clumped together, or patchy, then your pup may be suffering from hair loss. 

Some other symptoms include:

1. Patches of missing hair

2. Clumps or tufts of fur around the house

3. Excessive scratching and licking

4. Flaky skin or scabs on the coat

5. Bald spots on their face, neck, back, or tail

Why Is Your Dog Losing Hair?

When you notice bald spots on your pup, it can be worrisome. Alopecia, more commonly known as hair loss in dogs, is incredibly common and visibly evident. This type of fur-shedding may happen all over the body or show up as sparse patches; either way. There may be diverse causes for this, such as:

1. Seasonal Shedding
If your pup is losing more hair than usual, it could be due to seasonal shedding. Depending on the breed of your dog and the climate in which you live, changing seasons can cause excessive fur falling out. This is normal and usually nothing to be concerned about; just groom your pet more often during these periods. If your furry friend's shedding persists for too long or if you notice any bald spots, however, it may be time to consult with your veterinarian who will be able to determine if there are any underlying issues that could cause the additional hair loss.

2. Change Your Pup’s Diet
If your pup is losing hair due to poor nutrition, then changing their diet may be a beneficial solution. When purchasing food for your pet, look for high-quality brands that are specifically designed for dogs with sensitive skin and allergies. These formulas tend to contain more nutrient-rich ingredients which can help promote a healthy fur coat and reduce excess shedding.

3. Provide Regular Grooming
Regular grooming can help reduce shedding, relieve skin irritation, and keep your pup looking its best. Brush your pet often with a brush that is specifically designed for their coat type. Additionally, bathe them on a regular basis to remove dirt and debris from the fur and prevent skin infections.

4. Tackle Parasites or Allergies
Depending on the cause of your pup’s hair loss, you may need to take additional steps to fight parasites or allergies. If the source of the problem is fleas, ticks, or mites then it’s important to use a pet-safe preventative treatment on your furry friend. Similarly, if your pup has allergies, then avoid potential allergen sources in their environment and consult with your veterinarian about other possible treatments that can help.

5. Reduce Stress
If your pup’s hair loss is due to stress, then it’s important to address the source of the problem. Try to keep their routine and environment as consistent as possible and provide plenty of enrichment activities that can help reduce boredom and anxiety. Additionally, you may want to consider medications or supplements specifically designed for reducing stress in pets.

By following the steps outlined above, you can help ensure that your pup stays healthy and happy while helping to prevent further hair loss.

Common Diagnostic Tests

If your pup is suffering from excessive hair loss, then their veterinarian may suggest one of the following diagnostic tests:
3. Blood Tests
1. Skin Biopsies
This procedure involves taking a small sample of skin tissue and examining it under a microscope for signs of infection or irritation that could be causing the shedding.

2. Allergy Testing
Allergy testing is a useful tool for determining if your pup has any sensitivities that may be leading to hair loss. This procedure typically involves skin or blood tests which can help identify potential allergens that should be avoided in your pet’s environment.

3. Blood Tests
Blood tests are used to measure hormone levels and check for signs of underlying diseases like hypothyroidism that may be causing hair loss.


Dog hair loss is a common issue and can have several potential causes. If you notice that your pup is losing more fur than usual, it’s important to take action right away by consulting your veterinarian and examining their diet and environment. With the proper treatment and prevention methods, you can help keep your pup healthy and comfortable while reducing the risk of further hair loss.
