Common Dog Allergies and Their Causes

There are certain common dog allergies and symptoms that every dog owner should
know about.

The most prominent signs of allergy in dogs are itching and sneezing. Think twice
whenever you find your dog in long sneezing bouts.

As in humans, dog allergies (and diseases) may be the result of an improper dietary
regimen. Just like humans, dogs can also be the victims of heart diseases, diabetes,
etc.

According to veterinarians, one of the primary signs of a dog allergy is itching of the skin. Allergies can also affect a dog's respiratory track. Symptoms of allergy in the respiratory track system include wheezing, sneezing, and coughing. There are several different types of dog allergies. Below are the most common ones.

Allergies due to fleas Fleas are amongst the greatest cause of dogs allergies. It is a fact that dogs can become infected or contract an allergy through fleas. Most people don't think that these fleas can cause allergic reactions, but they can. It is important to get this clear; it is not the flea that actually causes the allergy. Rather, it is the saliva produced by the fleas. You should take your dog to your vet for a complete medical examination to determine if they are sensitive to flea saliva that could potentially cause an allergy.

Allergies due to foods Certain dog allergies are due to foods they are fed on. These are foods that their internal systems are unable to tolerate. Foods which might cause dog allergies include, but are not limited to, pork, fish, eggs, soy products, milk, wheat, beef, whey, corn, and artificial sweeteners. Chemical preservatives, which are usually placed in foods, are also known to cause serious dog allergies. Ideally, some dogs can develop allergies to foods that they are simply not used to. Signs of a food allergy include scratching the ears, behavioural changes, inflammations in the ear, shaking of the head, irritated skin, vomiting, sneezing and diarrhoea.

Atopic dermatitis This is a well known allergic skin disease affecting many dogs. Atopic dermatitis is usually caused by hypersensitivity of the immune system. Under certain conditions, the dog's immune system becomes highly hypersensitive to ordinary substances within their environments such as dust mites, moulds etc. A dog suffering from atopic dermatitis can be identified by excessive licking and chewing of its paws, abdomen, and rear feet. Visual signs of atopic dermatitis may appear as a saliva stain around the armpits, groin, and between the toes of its paws.

Allergies due to bacteria Bacteria are the leading cause of severe allergies in dogs. There are certain bacteria that have ability to thrive in dogs' skin. These are usually species of the Staphylococcus bacteria. For most dogs, this species of bacteria does not cause dog allergies; however, there are some species of dogs that are particularly susceptible to developing an allergy due to these bacteria. Hair loss is the clearest symptom of this type of allergy. This is usually followed by the development of ringworm on the dog's skin. Fortunately, it can be treated using antibiotics, especially by applying along the ringworm's marks.

Allergies due to bacteria In fact bacteria are the leading and most common causes of dog allergies. There are certain bacteria that are adapted to thrive well in the dog's skin. Such are species of Staphylococcus bacteria. They are widely known to cause severe allergies if not controlled. Not all bacteria cause dog allergies. There are dog species that are known to easily develop allergy due to presence of bacteria on their skin.
