Hair loss in dogs isn’t just a cosmetic issue—it can be a sign that something’s not quite right with your pet’s health. Whether your pup is shedding more than usual or showing patchy bald spots, knowing what’s normal and what’s not can help you respond quickly and avoid bigger problems.
Hair loss (also called alopecia) can have a range of causes, from seasonal shedding to parasites to allergies. So, if you’ve noticed your dog’s coat thinning or falling out, it’s important to pay attention and act early. In this article, I’ll walk you through the most common causes, how to tell when it’s serious, and what you can do about it.
Key Highlights
- Hair loss in dogs can be caused by anything from allergies to parasites or stress.
- Watch for signs like bald patches, skin irritation, or unusual scratching.
- Diet, grooming habits, and underlying health issues all play a role.
- Some breeds are more prone to shedding and hair loss than others.
- Consulting a vet early prevents the issue from becoming chronic.
- At-home treatments can help in mild cases, but persistent problems need professional care.
Is It Normal Shedding or a Real Problem?
Let’s start with something many dog owners overlook: dogs naturally shed. Some breeds, like Labradors or Huskies, blow their coats with the seasons. Others, like Poodles, barely shed at all. So a little fur on the couch might be annoying, but not unusual.
However, if you notice any of the following, that’s not just shedding:
- Bald spots or patches of missing hair
- Red, flaky, or irritated skin where the hair fell out
- Scabs, crusts, or sores
- Constant scratching or biting
- A foul odor coming from your dog’s skin
These are signs that something more than just normal shedding is going on. And it’s time to dig deeper.
Common Causes of Hair Loss in Dogs
Hair loss can be triggered by different factors—some minor, some more serious. Understanding what’s behind it is key to choosing the right solution.
Allergies Are a Major Culprit
Environmental allergens like pollen, mold, and dust mites can make your dog’s skin itchy and inflamed. Food allergies can do the same, especially if your dog reacts to common proteins like chicken, beef, or dairy. Repeated scratching or licking leads to thinning hair or bald patches, especially around the paws, belly, or ears.
Parasites Can Wreck a Coat
Fleas, mites, and ticks are more than just pests—they can cause serious skin irritation and even infection. Mange, caused by mites, can lead to large bald patches and inflamed skin. Flea allergy dermatitis is also incredibly common and causes dogs to scratch and chew fur off their backs and tails.
Hormonal Imbalances
Conditions like hypothyroidism and Cushing’s disease are often behind unexplained hair loss. These disorders affect your dog’s metabolism and coat health, leading to symmetrical hair loss along the flanks, lethargy, or changes in weight.
Stress and Behavioral Issues
Yes, dogs can lose hair from stress. Boredom, anxiety, or major changes (like a move or a new pet in the house) may lead to compulsive licking or biting—often referred to as psychogenic alopecia. The result? Patchy hair loss that doesn’t seem to make sense at first.
Don’t Rule Out Diet and Nutrition
Nutrition plays a huge role in skin and coat health. Dogs need a balanced diet with the right mix of fatty acids, proteins, and vitamins. If your dog is eating a low-quality or inappropriate diet, it can show up as dull fur, shedding, or baldness. Try to stick with dog foods that have real meat as the first ingredient and include healthy oils like salmon or flaxseed oil.

When You Should Call the Vet
Sometimes, hair loss isn’t something you can or should handle at home. If your dog’s skin looks inflamed or infected, or the hair loss is spreading rapidly, book a vet appointment. They may run tests to rule out:
- Fungal infections like ringworm
- Bacterial skin infections
- Endocrine disorders
- Autoimmune diseases
Early diagnosis can save you and your dog a lot of discomfort—and often, a lot of money in long-term treatments.
At-Home Care and Treatment Options
For minor or seasonal cases of hair loss, there are a few things you can do from home that might help bring your dog’s coat back to health.
Things You Can Try at Home:
- Oatmeal baths – soothe the skin naturally and help with mild itching.
- Coconut oil rubs – have antibacterial properties and moisturize dry skin.
- Supplements with Omega-3s – fish oil can improve coat shine and reduce inflammation.
- Switching to a high-quality diet – some pet parents see big changes with better food.
- Regular brushing – helps distribute natural oils and removes loose fur gently.
Be patient—hair regrowth doesn’t happen overnight. Even with proper care, it may take weeks to see visible improvement.
Breeds That Tend to Have Hair Loss Issues
Some breeds are just more prone to hair and skin problems than others. If your dog is one of the following, regular coat checks are a good idea.
- Bulldogs – tend to suffer from skin folds and infections.
- Dachshunds – can have genetic alopecia.
- Labrador Retrievers – heavy seasonal shedders.
- Chihuahuas – can get patchy hair loss on their backs.
- Boxers – prone to allergies and sensitive skin.
Knowing your breed’s tendencies helps you stay ahead of issues and prevent unnecessary vet visits.
Final Thoughts
Hair loss in dogs can be minor or a sign of something bigger. What matters most is how quickly you respond. Check your dog’s skin, keep track of symptoms, and when in doubt—call your vet. Don’t wait for things to get worse. The good news is, most cases of hair loss are treatable with a little effort, observation, and care.
The more you understand your dog’s body and behavior, the faster you can act when something seems off. It might be a simple fix—or a warning sign—but either way, staying informed and attentive makes all the difference.
