Types of dog allergies

Food Allergies in Dogs

Food allergies in dogs are a hypersensitive immune system response to specific components in their diet. These allergies are often triggered by ingredients like meat, milk, chicken, fish, corn, wheat, soy, eggs, or food additives.

To identify a food allergy to chicken or other ingredients, observe symptoms such as itching, vomiting, or diarrhea. These symptoms can appear immediately or several weeks after consumption.

It’s important to be aware of foods that are toxic to dogs to avoid potential dangers.

Atopic Allergy: Pollen, Dust Mites in Dogs

In this case, the allergy is caused by an airborne component that comes into contact with the dog via the respiratory tract. It is also an inadequate reaction of the immune system and the usual allergens are mites (dust), pollen or tobacco smoke.

How do I know if my dog has a pollen or dust mite allergy?

The most frequent symptoms such as itching, redness and inflammation should be monitored.

This type of allergy usually occurs in dogs between 1 and 3 years of age. It is very rare in dogs younger than 1 year or older than 3 years. Sometimes, it is thought that the dog has paw allergy because it scratches or bites mainly the paws or thighs. The allergy, i.e. the presence of pimples, eczema and itching can occur in several areas.

Dog Allergies to Fleas, Ticks, Wasps, or Bees

Allergies to fleas in dogs are quite common, also known as Dermatitis Allergic to Flea Bite (DAFB), and these allergies are caused by the saliva of fleas or ticks.

Insect stings from bees, wasps, spiders, or other insects can also cause allergies. Symptoms include itching, redness, and skin inflammation, along with frequent scratching.

What to do if your dog is allergic to fleas, ticks, wasps, bees or other insects?

If your dog has an allergy to fleas, ticks, wasps, bees, or other insects, the first step is to have a veterinarian examine the dog’s skin. Afterward, you should thoroughly treat and eliminate all fleas, ticks, and their feces from your dog’s skin or coat.

In cases of such allergies, it is crucial to be diligent in implementing regular anti-parasitic measures to avoid the discomfort of an allergic outbreak in your dog.


Dermatological Allergies: Skin Allergies in Dogs

Las alergias dérmicas son aquellas en las que el alérgeno contacta directamente con la piel del perro. También se conocen como alergias ambientales en perros. Son una de las alergias más comunes en perros junto con las alimentarias.

What causes my dog to have skin allergies?

The allergen, that is, the substance that triggers the allergy, can be found in various everyday objects and products, such as shampoo, lotions, insecticides, collars, fabrics, cleaning products, and medications. Observe the common signs of allergies, including itching and frequent scratching.

The primary treatment is to avoid the allergen as much as possible. To relieve itching, redness, and inflammation, veterinarians often prescribe antihistamines. When dealing with skin allergies in dogs, pinpointing the allergen that causes the reaction is the main challenge.

Your veterinarian can perform a physical examination and use blood tests or intradermal tests to identify the allergen responsible for the allergy.

Medication Allergies in Dogs

Medication allergies occur due to an immune system hypersensitivity to a component in a drug. These allergies typically manifest as itching, facial swelling, apathy, and vomiting.

In severe cases, they can lead to an acute allergic reaction, known as anaphylactic shock.

How to treat dog allergies?

When symptoms appear, you must consult a veterinarian for allergy diagnosis and treatment. As you can see, there are many types of dog allergies, including food allergies, insect allergies, environmental allergies, and skin allergies. Once you know the specific allergen responsible for the dog’s allergy, the treatment becomes straightforward – avoid the allergen. In the meantime, diligent prevention is essential.

Tips for Preventing Dog Allergies

  • In the case of food allergies, when changing your dog’s diet, do it gradually to easily notice any reactions and identify new allergens.
  • Regularly administer parasite control treatments to prevent flea and tick bites and infestations that might be mistaken for allergies.
  • Using air purifiers in your home is beneficial for both humans and pets, as they remove various allergens from the environment.
  • When changing your dog’s shampoos or lotions, introduce new products gradually to detect and prevent allergic reactions.
  • Observe your pets for any unusual behavior, frequent scratching, or signs of discomfort. After outdoor walks, check their paws and examine their skin to detect and prevent any anomalies.
