Why Is My Dog Losing Hair?

Shading occurs. This is a fact! You can always count on them losing their grip when spring or fall rolls around and dogs shed their seasonal coats. 

Environmental factors such as temperature, nutrition, hormonal change, and stress can also affect canine coat loss.

Let me clarify that sometimes losing hair is normal, and not a big deal but during dog hair growth, thinning hair with mild to severe bald patches is also called “alopecia”.

Now, this is important that if your dog suffered from excessive hair loss, sheds a little too much, or is unusual, you may want to check if they have this situation.

Why do dogs lose hair too much?

6 Major Causes of Hair Loss in Dogs

There are many factors that can cause a dog to lose hair, including allergies, infections, parasites, seasonal effects, and hyperadrenocorticism. 

Treatment depends on the underlying cause of dog alopecia and usually requires a veterinary diagnosis and recommendation.

1. Allergies

Allergies are one of the most common causes of dog itchiness and hair loss in dogs. Allergic reactions develop in dogs just like in humans, and some common symptoms include itchy skin and hair loss.

The most common allergies in dogs are environmental allergies such as pollen, mold and dust mites, food allergies, and flea allergies.

Here’s what I mean If your doctor suspects an allergy, they may suggest flea control, medications to control itching, allergen avoidance, or dietary changes to rule out types of food allergies.

Food allergies can only be treated by doing a food trial for at least eight weeks. 

If your vet suggests your dog for a food trial that involves a limited-ingredient meal plan or treatment, it’s important to make sure your dog doesn’t eat anything else during the trial.

A chicken treat or a stolen bite can confuse the results. If the underlying cause is allergies and they are treated appropriately, your dog’s hair should grow back and the itching should end.

2. Seasonal shedding

In some cases, seemingly extreme dog shedding is normal. A dog’s coat sheds when the individual hairs become damaged, or seasonally when the weather warms up. Many dogs shed hair throughout the year.

Similarly, some dog breeds, such as Labradors, and huskies grow thick winter undercoats that they shed in the spring.

Let me lift the veil for you that seasonal shading is often reduced if you live in a temperate climate. 

If you notice hair falling off your dog is too much, brushing your dog twice a week can remove and control the hair.

3. Mange/Parasites

Mange mites are specific for an itchy skin infection. Mites are microscopic creatures that survive on the surface of the skin or in hair follicles or are dangerous for dogs.

How? These can cause dog hair loss and itching when the dog’s skin is chewed. Some mites, such as tiny scabies mites, are highly contagious to both humans and other dogs.

Other mites, such as Demodex mites, are not contagious but still cause hair loss in dogs and may require appropriate treatment.

A common cause of dogs losing hair is fleas. Fleas can make dogs itchy enough to scratch their hair in places. 

Mites and fleas are highly contagious, so if you find any parasites on your dog that have already been transmitted to your home and other pets.

Let me tell you if you find an indication of fleas or mites, your doctor may recommend an antiparasitic medication and offer suggestions for ridding your house pests.

4. Bacterial/Fungal Infections

Bacteria and yeast are normal residents of the canine skin, but sometimes they can get out of control and cause infections.

These fungal infections on the skin can cause hair loss, itching, redness, odor, and other skin infections. Sometimes, infections cause pimple-like boils which also cause pain in dogs.

A fungus that causes hair loss and small parts of infection can also contract ringworm in dogs. No, it’s not actually a worm. Red, itchy or itchy spots are a reason to visit the vet.

Here’s a how-Your doctor will do a thorough examination and recommend some tests if necessary he prescribes veterinary medicine, antibiotics, or antifungals to treat the infection on the dog’s skin.

5. Hyperadrenocorticism

Hyperadrenocorticism, also called Cushing’s disease. It is a situation in dogs that become a source of losing hair due to increased levels of the hormone cortisol.

Cushing’s disease symptoms include darkening of the skin, higher rate of thirst and urination, frequent skin infections, and an enlarged stomach. It is most common in middle-aged to elderly dogs.

But what if your dog is showing any of these symptoms, take them to the vet so they can be treated properly.

6. Other Underlying Conditions

If a shedding dog is losing hair all over its body, the issue may lie under the hood.

We all know that the skin is technically the largest organ in the body, and it needs a lot of nutrients to stay healthy. If your dog has an underlying medical condition, his hair and fur may be impacted badly.

Hormonal conditions: Hypothyroidism, Adrenal gland disorders, Growth hormone disorders

They can all lead to hair loss in dogs. If your doctor suspects an internal issue as the reason for the hair loss, they may recommend laboratory tests and possibly X-rays or ultrasound imaging to identify the cause.
