Why Do French Bulldogs Lose Hair?

French Bulldogs, like all dogs, lose hair for a variety of reasons, including genetics, skin conditions, parasites, hormonal imbalances, and dietary deficiencies. Some of the common causes of hair loss in Frenchies include allergies, mange, hypothyroidism, and an underactive adrenal gland. To determine the underlying cause of hair loss, it’s important to seek a veterinarian’s advice. With the right diagnosis and treatment, hair loss can be managed and prevented.

Hair Loss and French Bulldogs

Hair loss, aka shedding, is normal in French bulldogs. However, excessive shedding is a cause of concern. Underlying causes like allergies cause itching and scratching, leading to hair loss. Moreover, mange is a skin condition caused by mites. Hypothyroidism is a hormonal disorder that causes hair loss, while an underactive adrenal gland causes a condition known as adrenal insufficiency, which results in hair loss.

Are French Bulldogs Prone To Hair Loss?

Yes, French Bulldogs are prone to hair loss. Their unique body types, with wrinkles and folds, make them susceptible to skin irritations and infections. Additionally, the dense, short coat on Frenchies provides little insulation, making them more prone to skin problems and hair loss. To minimize the risk of hair loss and keep your Frenchie‘s skin and coat healthy, it’s important to provide a balanced diet, proper grooming, and regular veterinary care.

Reasons why your French Bulldog might be losing hair

There are several reasons why your French Bulldog might be losing hair, and some of the common ones include the following: 

  1. Genetics.
  2. Skin conditions like allergies, mange, and skin infections.
  3. Hormonal imbalances that cause hypothyroidism and an underactive adrenal gland.
  4. Dietary deficiencies such as a lack of essential fatty acids.
  5. Stress.
  6. Aging.

Flank Alopecia Seasonal Baldness in Bulldogs and French Bulldogs

This is a cosmetic condition that affects the hair follicles due to reduced sunlight exposure. Melatonin and prolactin hormones, and follicular hormone receptors, are the primary suspects responsible for the condition. It mostly affects adult Frenchies and is not itchy. Fortunately, as the season changes and your Frenchie gets more sunlight exposure, the hair grows back. Alternatively, melatonin supplements can help the hair grow back.

Hair loss due to Parasites

Parasites like ticks and fleas do lead to hair loss in Frenchies and other breeds. These parasites cause itching, redness, and inflammation of the skin, leading to hair loss. Treatment options may include medicated shampoos, topical or oral medications, and changes to the dog’s diet and environment, but you should consult your vet beforehand.


Allergies are a common issue, and the allergens include food like wheat and corn and environmental allergens such as pollen or dust mites and flea bites. The allergens cause skin irritation which causes your pup to scratch and bite its fur, leading to hair loss. To determine the cause of the allergy, a veterinarian may recommend an elimination diet, skin tests, or blood tests. Treatment options may include changing the dog’s diet, prescribing antihistamines or steroids, or allergen-specific immunotherapy (allergy shots). It is important to seek veterinary care to properly diagnose and treat the underlying cause.

Dermatitis, or skin inflammation, is a common issue among French Bulldogs, especially if they have weak immune systems. It is mainly caused by allergies and gastrointestinal issues. To diagnose the underlying cause of dermatitis, a veterinarian performs a skin culture, an allergy test, or takes a biopsy of the affected skin. Treatment options are similar to hair loss due to parasites.

Bald Patches

Bald patches on your Frenchie’s coat are usually the manifestation of alopecia. As noted earlier, the patches are common during winter and are mainly cosmetic. They do not require treatment; however, melatonin supplements and medicated shampoos do help the hair grow back. If you notice bald patches during sunny seasons after your pup has had enough sunlight exposure, then consult your vet. Probably allergies may be causing the bald patches.

Hormonal Problems

Hair loss in French Bulldogs due to hormonal problems is caused by conditions such as hypothyroidism, adrenal gland disorders, or hormone imbalances. Common symptoms include thinning hair, slow hair growth, or hair loss in specific areas. Hormonal problems require professional help to identify and address because they are gradual and unnoticeable at first. Your vet is best qualified to administer the proper medication after a checkup.


Mange is a common skin condition caused by mites. The mites cause itching, redness, and crusty skin, leading to hair loss. There are two main types of mange in dogs: demodectic mange and sarcoptic mange. Demodectic mange is caused by a mite that is usually present on the skin of healthy dogs but overgrows in dogs with a weakened immune system. Sarcoptic mange, also known as scabies, is caused by a highly contagious mite that spreads from dog to dog. Medicated shampoos, topical creams, or oral antibiotics are the popular treatment for mange.

Poor Nutrition

Hair loss due to poor nutrition is caused by a lack of essential vitamins and minerals in your Frenchie’s diet. Additionally, it may be due to medical conditions that affect a Frenchie’s ability to absorb certain nutrients from their food. Symptoms of nutrient deficiencies include dull, brittle, or thinning hair, as well as slow hair growth. It is important to feed your Frenchie a balanced, nutritionally complete diet to ensure optimal health and prevent hair loss due to poor nutrition.
