Allergies in dogs: causes and symptoms

Allergies in dogs are a reality that can significantly impair the dog’s quality of life. There are actually many different types of allergies that can cause a variety of symptoms.

Allergies affect many dogs,  and they mainly lead to itching of the skin and ears and eyes. They can appear in the form of digestive problems and make your pet’s life more difficult than it needs to be.

Skin allergies, food allergies and environmental allergens can be problems for dogs and their owners. As if that were not enough, some of these allergies may actually overlap.

Skin allergies, also known as allergic dermatitis, are most common when it comes to allergies in dogs. There are three main reasons for this type in dogs:

  • Allergic dermatitis caused by fleas
  • Food allergies
  • Environmental allergens

Allergic dermatitis can, as I said, be a reaction to fleas, or more precisely to the saliva of said fleas. This leads to severe itching, especially at the base of the tail. The skin may become red, inflamed and form scabs.

Food allergies can also cause itchy skin.  The ears are the paws are the most common places that dogs are disturbed by this. Gastrointestinal symptoms may also occur.

Environmental allergens, such as dust, pollen and dirt, can cause many reactions on the skin. In the majority of cases, these allergies are seasonal, so the itching may only appear during certain periods of the year.

Like food allergies, the body parts that mainly affect the paws and ears. However, the symptoms can also appear in other areas of the body, such as the mouth, groin and around the eyes.

All skin allergies pose a risk of secondary infections. When the dog itches, bites or licks the skin, it can be exposed to yeast or bacterial infections, which require further treatment.

Food allergies are not as common as people think.  The symptoms of the skin can vary, but include itching and swelling of the face.

Here, too, the dog may experience gastrointestinal problems, such as vomiting, diarrhea, or both. In rare cases, it can even lead to anaphylactic shock, which is similar to the allergic reaction in people who do not tolerate peanuts.

Furthermore, most people think that their dog is sensitive to certain foods when they say that it is allergic. This is actually called food intolerance.

Food sensitivity does not suggest an immune response, unlike actual allergies. Instead, it is a gradual reaction to a certain ingredient in the food, such as meat, eggs, wheat, corn, soy or milk.

Dogs with food intolerances may experience several symptoms.  They include gastrointestinal signs, such as vomiting, diarrhea or dermatological conditions, including itching, lost fur and chronic infections of the ears and paws.

However, some actual allergies in dogs are linked to food, which can lead to digestive problems and gastrointestinal discomfort.

Acute allergic reactions in dogs are the most alarming. Dogs, like humans, can experience anaphylactic shock if they experience an extreme allergic reaction. This can be fatal if not treated in time.

Being stung by bees or reacting badly to vaccinations can lead to anaphylactic shock in dogs. Therefore, it is important to observe the dog after receiving vaccinations, new drugs or new food. This condition is fortunately uncommon in dogs.

Dogs can also develop a rash or swelling on the face as a result of an allergy. Swelling of the face, lips, eyelids or outer ear can be acute, but rarely fatal. Your veterinarian can treat these reactions with antihistamines.

The symptoms of allergies in dogs depend on the cause. A dog that, for example, suffers from anaphylactic shock will have low blood sugar levels after the shock. This is very different from a skin problem.

In general  , the following symptoms may be a sign of an allergic reaction:

  • Itching
  • Rash
  • Swelling of the face, ears, lips and eyelids
  • Red, inflamed skin
  • Diarrhea
  • Vomiting
  • Yawning
  • Itching in the ears
  • Chronic ear infections
  • Itchy, watery eyes
  • Constant licking

The difficult thing is that these symptoms can also be due to another cause. However, it is important to see a veterinarian to get an accurate diagnosis.
