What are the dog's allergies? Symptoms, causes, and types.

Allergens cause different allergies. Sometimes, these allergens are present in food, sometimes on other dogs, and most of the time, the surrounding environment gives refuge to these allergens. Depending on the type of allergen, allergies are also variable, and overlapping their symptoms increases the complication. Mainly they are three types.

  • Flea allergy dermatitis
  • Food allergy
  • Environmental allergies

Flea allergy dermatitis:

This allergy is primarily transmitted by fleas. The main signs of this allergy are inflammation, scrubbing, and redness at a particular infected body phighlymost vulnerable part of the body in this regard is the dog’s tail or sometimes its ear. The dog is extremely irritated and has started scratching the affected area. Technically, your dog is not allergic to the flea itself; it is the flea’s saliva that comes into contact with your dog’s skin after it bites it. And to recognize that bite is too tricky as flea does not stay in body part after biting it. But your dog starts licking or biting that part madly.

If you look closely, you may notice dirt on the allergic parts of the flea, such as the tail and sometimes the flea itself.

Environmental allergies:

Environmental or seasonal allergies in dogs are commonly inherited, and the term “atopy” is used to describe this condition. These allergies vary from breed to breed. Some canines are vulnerable to only one kind of plant pollen, but others might be the prey of more than one plant. Seasonal allergies occur due to dust or dirt particles and mainly pollens that release by plants. Your dog may develop an allergy to such allergic pollens after inhaling them. It depends upon the surrounding plants or the plants in your yard.

Allergies in dogs are most commonly caused by plant pollen inhalation, but they can also be caused by dirt contact with the skin, depending on the sensitivity of your dog’s skin.

Food allergies in dogs:

Food allergies are as common in dogs as some humans are allergic to peanuts or shellfish. It is essential to note that if your dog is allergic to a specific food, it does not mean that the food is toxic or something is wrong. It simply means that your dog’s digestive system does not support the proteins or carbohydrates present in it.

Food allergies in dogs are low compared to other allergies. As veterinarians claim, only 10 percent of dog allergies occur due to food, among all other allergies. It is also because food allergies can cause skin itching in addition to digestive reactions. And that is the reason people usually mimic it with environmental allergies.

The protein inside chicken, beef, or other meat is the prime reason for food allergies in dogs.
