What Causes Hives in French Bulldogs? Treatments & Preventions

Hives in French Bulldogs are usually caused by an allergic reaction to foods, medications, pollen, insect stings, or chemicals. These allergens trigger the release of histamines, leading to swelling and itching. Hives appear as round, raised welts on the skin that are often red and can cause significant discomfort. Stress can also sometimes exacerbate or trigger hives in predisposed dogs.

What are Hives in French Bulldogs?

Hives, medically known as urticaria, are a type of allergic skin reaction that causes localized patches of swelling that are usually very itchy. In French Bulldogs, hives can appear suddenly and often become noticeable due to the shortness of their coat. They can be accompanied by other symptoms of allergies, such as facial swelling, particularly around the eyes and lips, and they may come and go quickly.

10 Common Causes of Hives in a French Bulldog

Insect Bites or Stings

Insect bites or stings, especially from bees, wasps, or mosquitoes, can cause an allergic reaction in French Bulldogs, resulting in hives. The body’s response to the insect’s venom can lead to immediate swelling, redness, and itchy bumps on the skin.

Food Allergies

French Bulldogs can develop hives due to an allergic reaction to certain foods or additives. Common culprits include beef, dairy, wheat, soy, and artificial colorings or flavorings. Food allergies can cause gastrointestinal symptoms as well as skin reactions like hives.


Some French Bulldogs may have allergic reactions to medications, which can manifest as hives. This includes reactions to antibiotics, vaccines, or flea and tick preventatives. Hives can appear shortly after administering medication if the dog is sensitive to it.

Contact Allergens

Direct contact with allergens like certain shampoos, grooming products, or household cleaners can cause hives in sensitive dogs. The skin may react to these irritants with raised, itchy welts wherever the substance has made contact.

Environmental Allergens

Pollen, mold, dust, and other environmental allergens can lead to hives in French Bulldogs. When dogs are exposed to these allergens, they may develop atopic dermatitis, which can include hives as a symptom, along with chronic itching and skin infections.


Stress can weaken the immune system and may lead to various skin conditions, including hives. French Bulldogs, being particularly sensitive dogs, can experience hives in response to stressful events such as moving, traveling, or changes in their home environment.

Extreme Temperatures

Exposure to extreme temperatures, whether hot or cold, can trigger hives in some French Bulldogs. This physical reaction to temperature changes can cause the skin to break out in hives due to the body’s histamine release.

Fabric and Materials

Certain fabrics or materials, including carpets, bedding, or clothing, can cause allergic reactions in French Bulldogs. The textures or chemicals treated on these materials may irritate the skin and lead to hives.


Fleas, ticks, and mites are not only irritating but can also cause allergic reactions, leading to hives in French Bulldogs. The allergic reaction is typically to the saliva of the parasite and is known as flea allergy dermatitis.

Vaccine Reactions

Although vaccinations are crucial for a dog’s health, some French Bulldogs may have an allergic reaction to certain vaccines. This immune response can lead to hives, swelling, and discomfort, usually occurring soon after the vaccination is administered.

Home Remedies

  • Cool Bath: Giving your French Bulldog a bath with oatmeal-based dog shampoo can help soothe the skin and reduce itching.
  • Cold Compresses: Applying cold compresses to the affected areas can provide immediate relief from itching and swelling.
  • Aloe Vera: Pure aloe vera gel, which has natural anti-inflammatory properties, can be applied to the hives to soothe the skin.
  • Dietary Adjustments: If the hives are suspected to be caused by a food allergy, remove the potential allergen from the diet and observe for improvements.
  • Apple Cider Vinegar: A diluted apple cider vinegar solution can be used as a topical spray to help soothe itchy skin, provided the skin is not broken.

Professional Treatment

  • Antihistamines: A veterinarian may prescribe antihistamines to quickly reduce the symptoms of hives and control the allergic reaction.
  • Corticosteroids: In more severe cases, corticosteroids might be used to reduce inflammation and treat acute symptoms of hives.
  • Elimination Diet: Under a vet’s guidance, an elimination diet may be conducted to identify food allergies by systematically removing and then reintroducing potential allergens.
  • Allergy Testing: Allergy testing can be recommended by a veterinarian to determine the specific cause of the allergic reaction and develop a targeted treatment plan.
