Allergy in dogs, symptoms, types and treatment



Have you ever questioned the existence of allergies in dogs? , it is very likely not.

Surely from time to time you have heard your furry sneeze or seen him scratch more than necessary, but … can dogs have allergies?

Short answer, yes.

After all, they are living beings like you and me, so they can be sensitive to pollen, certain ingredients in food, or the bite of a parasite among many other things, for example.

As with us, the type of allergy and the severity with which it interacts with the furry will be very different and will depend on how its body reacts to that external agent that is affecting it.

This can range from mild irritation to, in the worst cases, death.

To better understand what allergies in dogs are, I have prepared this post where I tell you the most common types of allergies in dogs, what their symptoms are, and the treatment that I usually follow.

Pay attention we start!

Types of allergy in dogs

An allergy is an exaggerated reaction of the immune system, in this case, that of your dog, to a foreign and external body that under normal circumstances does not cause any type of damage.

So why if it doesn’t normally cause harm, now it does?

This substance, known as an allergen, interacts with your dog’s immune system by stimulating it to generate a series of special antibodies.

When said allergen comes into contact with your furry again in any way, the body will generate said antibodies, which when joined to the allergen will cause the allergic reaction.


What can be an allergen for your dog?

Pollen that is scattered in the places where you walk
Some ingredients in the food
Bites from external parasites such as fleas or ticks can cause allergies

With this in mind, I am going to tell you about the different types of allergies in dogs and what causes them:


Food allergies in dogs

As its name suggests, this type of allergy in dogs is caused by one or more ingredients in their food, which cause an allergic reaction.

This type of canine allergies can appear in dogs of any age and do not follow any type of seasonality, that is, they can appear at any time of the year.

For the furry’s body to consider this ingredient as an allergen, it is essential that it is presented to the animal periodically, therefore, if it always eats the same food, it can end up generating some type of food allergy.

The most common ingredients that cause allergies to a dog are:

  • Wheat
  • Chicken
  • Eggs
  • Milk
  • Atopy in dogs

This type of allergy has as its causative allergen something that the dog has sniffed or smelled.

Atopic allergy affects around 15% of dogs and, as I have mentioned before, that your dog suffers from this type of allergy is due to a hypersensitivity of the same to the causative substance.

The most common allergens causing this atopy are:

  • Pollen
  • Herbs
  • Cigarette smoke

As you can see, the first two are harmless, but the third can not only cause allergies but also significantly affect your furry’s lungs.

Spring allergy in dogs is a clear example of this type of atopic allergy.

During this time of year, the flowering of plants is greatest and therefore the pollen that is released can cause a lot of allergies.

Atopic dermatitis in dogs

This type of allergy in dogs appears when some type of allergen makes contact with the skin, which causes an allergic reaction.

As a consequence of such contact, the skin becomes inflamed and the dog itches intensely, irritates and, in some cases, hurts.

Allergy symptoms in dogs

Depending on the causative agent of the allergic reaction, the symptoms can be localized in a specific area or systemic.

The most normal is that its evidence is reflected in the skin or through digestive problems.

These are the most obvious external symptoms of an allergic reaction:

  • Skin irritation
  • Pustules on the skin
  • Frequent scratching of the ears
  • General discomfort
  • Rashes
  • Pimples and redness
  • Constant itching
  • Sneezing
  • More frequent shaking of the head                                                                                                                                                                                                                                                                                                                                        Treatment of allergy in dogs                                                                                                                                                                                                                                                                                                                                                            In order to know the treatment to apply to your dog, the veterinarian must diagnose the type of allergy that it has.

When you arrive at the clinic, he will ask you what symptoms he has, review the dog’s history (if he is a regular patient) and perform a physical exam.

Another thing that the vet will take into account is the time of year that you are in at that time since some of them are seasonal.

During the physical examination, some type of external parasites such as fleas or ticks may be found, so that could be the cause of the allergy.

Also, keep in mind that your dog can have several allergies at the same time.

If the vet cannot recognize what allergy your dog may have at the first “glance,” then they will need to perform allergy tests on dogs, such as allergy tests.

Once diagnosed, the corresponding treatment will be applied.

If the cause of the allergy is some type of food, the most common thing is to eliminate that type of food and see how the dog reacts.

Has the allergy gone and is it getting better? That was the cause of the allergic reaction.

For the rest of the allergies, the veterinarian with the results of the tests carried out will proceed to apply antihistamines for dogs.

This type of product does not eliminate the allergy but it does reduce the symptoms that the dog may suffer.

Along with this, creams, shampoos, and lotions are also recommended to help alleviate allergy symptoms.

Once the type of allergy is known and with the appropriate treatment, the dog can lead a normal life, however, it may have to continue taking medications to alleviate the symptoms.
