What is an allergy?

When the immune system over-reacts with hypersensitivity to particular substances, this state is called allergy. These substances are known as allergens. The protein is considered to be the most widespread allergen for humans and canines. Plant protein, insects, and food protein are usually the cause of allergies in canines.


The immune system protects dogs from the harmful effects of germs and bacteria. But when the allergic situation is caused, this very immune system fights back with over-reaction. This immune response is unnecessary and causes problems for dogs and their parents.


Types of Allergies in Dogs

When the immune system falsely recognizes the allergens and responds ill-logically, the allergy is caused. There are various types of canine allergies all around you. The most common ones are skin, food, and environmental allergies. The most confusing thing for humans regarding the allergy is their symptoms.


The allergies and their symptoms are overleaping, and they make it difficult for the parents to recognize them. Let's start reading about these types of allergies to know them better and react accordingly:


1. Skin Allergies

Dermatitis or skin allergy is the most common type which your canine buddy has to suffer from. Skin allergy is mostly caused by three different factors with the inclusion of food and environment. When the food and environmental agents affect the skin of your buddy, we add these to dermatitis. Following are the three types of canine allergies of skin:

A) Flea allergy dermatitis

B) Food allergy dermatitis

C) Environmental allergens dermatitis

A) Flea allergy dermatitis

When fleas are on their skin, they will have to bite and scratch it, and the results are fleabites. Most dogs are allergic to flea saliva, and their presence on dogs' skin is enough to make them crazy scratchers. You can examine the skin and will come up to see flea dirt or flea itself when your dog scratches a lot.


The most common place is under their tail and on the skin under the stomach. The skin will become bloody red, and the continuous scratching might cause wounds. You need to save them from getting an infection in such a condition. It would help if you rushed to the medication or vet recommendations right away.

B) Food allergy dermatitis

Food allergy is caused by a particular food protein that makes the immune system go crazy. The commonplace for the allergy is their paws and over their ears. Food allergy also comes with gastrointestinal symptoms. You must be cautious about that food again in the future, or you could get the situation slipping out of hand.

C) Environmental allergy dermatitis

Atopic dermatitis or atopic allergy are other names for environmental skin allergy. The most common causes are dust particles, pollen, and mold. The environmental allergy has the same symptom as food allergy, but it adds scratching on the wrists, ankles, muzzles, and underarms. Their eyes and toes are also not safe from this itching.

When the allergy starts at a particular time of the year or in certain conditions, it is your cue to consult your vet and get it treated.


2. Food Allergies

The food allergy can show the symptoms of dermatitis or gastrointestinal issues, or both at the same time. A food allergy can become fatal, like anaphylaxis, to make your dog suffer the most. That's why one should consult the vet and get them tested for particular types of food allergies.


When you want to offer them a new recipe with good nutritious value, it is best to go slow. Only add a small amount of the new food to their diet and look for the signs and symptoms of allergy. If there are none, you are good to go. But if you find any, leave this idea at once for the safety of your canine friend.

3. Acute Allergic Reactions

Anaphylactic response to bee stings and the vaccine could claim the life of your best buddy if you don't act accordingly. The rarity of this phenomenon makes the parent comfortable, but still, the chances are there. It would be best if you remained cautious about the new medication and drug administration.


The swelling on the face or other body parts could be the first phase of anaphylactic response. You must never take chances on canine allergies and should rush to the vet at once. The swelling and itching because of a particular food and environmental allergen could pose some serious threat, and you shouldn't take them lightly.


Diagnosing Canine Allergies

Food allergy is the easiest to find out for parents and vets. The novel proteins diet for 12 weeks will let you know about the allergens. But the other types of allergies will require tests and some certain changes in the environment. You should follow vet recommendations strictly to know the real cause and type of allergy.
