French Bulldog allergies: symptoms and treatment

French Bulldog allergies are one of the most common diseases of this breed. Such a reaction indicates an increased sensitivity of the dog to some form of irritant such as food, medicines household chemicals, parasites, etc.. When the animal’s body is exposed to an allergen, various symptoms begin to appear, indicating an allergic reaction. Signs of allergy are different and similar to the symptoms of other diseases, so only a veterinarian can establish an accurate diagnosis.

Types of French Bulldog allergies

Food allergy

An allergic reaction of the body can manifest itself both to food already present in the dog’s diet or to newly introduced ones. Allergies are most common in puppies under 6 months of age. The animal’s immune system often reacts to proteins (chicken, beef, veal, fish), milk, eggs, yeast, soy, red vegetables, fruits, and fish oil. This type of allergic reaction has no common symptoms and can manifest itself in different ways.

Moreover, intolerance may not appear immediately, but after a certain time. It is impossible to determine the presence of an allergy by a blood test or microscopic analysis of a sample of the skin. Only special tests, based on trial and error, are effective at identifying the specific agent causing the allergic reaction.

Contact allergy (dermatitis)

Such a reaction in the French Bulldog can occur when the dog is exposed to household chemicals and cosmetics (shampoos, balms, dog care products). Sensitive skin may cause your dog to react to some grooming products. If the French Bulldog is allergic, it is recommended to choose hypoallergenic shampoos, lotions and creams for him. Dermatitis can also manifest itself as a reaction to the fur, dandruff or skin particles of other animals or from humans.

Allergy to medications

The main allergens in this group are antibiotics, barbiturates, sulfonamides, pyramidone, morphine, foxglove, alfalfa extract, novocaine, vitamins with brewer’s yeast, serums and vaccines with live bacteria.


When the immune system becomes dysfunctional, the French Bulldog’s body can start producing its own allergens.

If vomiting occurs, you need to stop feeding the dog for 24 hrs and monitor the well-being and behavior of the dog.

Therapy includes three main areas of intervention: identification and elimination of an irritant, correction of a hypersensitive state, prescription of symptomatic drugs against allergies.

Identification of an allergen in case of food intolerance is carried out using special tests. After determining the reason, the dog is submitted to a protein-free diet and sweets are totally excluded.
