My Dog Has Severe Skin Allergies What Can I Do

Dogs can suffer from a variety of skin allergies, and it can be frustrating and difficult to figure out the cause and the best way to treat it. If your dog has severe skin allergies, it is important to understand what might be causing the problem and what you can do to help alleviate their symptoms. In this blog post, we will go over a list of common causes of severe skin allergies in dogs and what you can do to help your furry friend feel more comfortable.

  1. Flea Allergies: One of the most common causes of severe skin allergies in dogs is flea allergies. When a dog is bitten by a flea, their body can have an allergic reaction to the flea’s saliva. This can cause severe itching, redness, and hair loss. To treat flea allergies, it is important to use a flea preventative medication such as a monthly topical treatment or oral medication. Additionally, keep your dog’s environment clean and free of fleas by vacuuming and washing their bedding regularly.
  2. Food Allergies: Another common cause of severe skin allergies in dogs is food allergies. Food allergies can be caused by a variety of ingredients, such as chicken, beef, corn, or soy. To diagnose a food allergy, your vet may recommend an elimination diet where you switch your dog to a limited ingredient diet, and then slowly add back ingredients one by one to determine which ingredient is causing the allergy. Once the allergen is identified, you can switch to a food that does not contain that ingredient.
  3. Environmental Allergies: Environmental allergies can also cause severe skin allergies in dogs. These can include allergies to pollen, mold, and dust. To help alleviate your dog’s symptoms, try to keep their environment as clean and allergen-free as possible. This might include keeping windows closed during high pollen seasons and using air filters. Your vet may also recommend antihistamines or steroids to help reduce your dog’s allergic reaction.
  4. Contact Allergies: Contact allergies occur when a dog’s skin comes into contact with a specific allergen. This can include things like rubber, plastic, or certain fabrics. To diagnose a contact allergy, your vet may perform patch tests to determine which substance is causing the reaction. Once the allergen is identified, you can avoid contact with that substance and use medicated shampoos or creams to help alleviate your dog’s symptoms.
  5. Atopic Dermatitis: Atopic dermatitis is a chronic skin condition that is caused by an overactive immune response to allergens. It is characterized by severe itching and red, inflamed skin. To treat atopic dermatitis, your vet may recommend a combination of medications, such as steroids and antihistamines, as well as special shampoos and moisturizers.

In conclusion, severe skin allergies in dogs can be caused by a variety of factors, including flea allergies, food allergies, environmental allergies, contact allergies, and atopic dermatitis. To help alleviate your dog’s symptoms, it is important to work with your vet to determine the cause of the allergy and follow their recommendations for treatment. Remember to keep your dog’s environment as clean and allergen-free as possible, and be patient with your furry friend as they may take some time to heal.
