Dog Skin Allergies Types And Causes

By Jennifer Gretson


More dogs are developing allergies today than ever before. Some estimates claim that as many as one of every seven canines display allergy symptoms. Further, dog skin allergies are the most common reason owners bring pets in to see a veterinarian. Heredity is thought to be a contributor to these problems. So is breed, as some kinds are more likely to have issues than others.

An allergy is a negative reaction after exposure to environmental stimuli, food, or an inhalant. Whatever the offending substance is that dogs are exposed to is termed an allergen. This allergen stimulates the immune system of a dog to perform a hypersensitive or allergic reaction.

Dogs must come into contact with a substance at least twice before they can have a reaction from it. During the first time of exposure, the immune system manufactures antibodies. Afterwards, when exposure again occurs, an antibody directed reaction takes place that produces histamine, a chemical mediator.

Humans normally have the majority of their symptoms present themselves in the respiratory tract. Dogs develop skin symptoms instead. Frantically itching is a very telling sign of problems. Beyond scratching, dogs can also develop short tempers and be generally unpleasant because of their suffering.

There are two categories of hypersensitivities. The first happens immediately, only minutes after exposure, and causes the formation of hives. Severe types of immediate responses can cause anaphylactic shock, weakness, collapse, breathing difficulties, diarrhea, vomiting, and death. Delayed response types happen from hours to days after exposure. The main indicator of this type is an extreme itching sensation.

Canine allergies have four main causes. The first is fleas or other insects that bite. The second is inhaled forms of allergens such as molds, dust mites, pollen, and grasses. The third is the result of consuming certain foods or drugs. Lastly, irritation may be the result of direct physical contact with a substance.

Hives are a common problem in dogs. They occur with the immediate reaction type response and appear as raised circular areas. Hairs can start to stick out in patches. Eyelids also may start to swell. Hives can develop around a half hour after exposure and disappear by the same time the next day.

Their cause can be soaps, insecticides, antibiotics, vaccinations, or insect bites. If they seem to appear and then disappear they are probably caused by something within the environment. When problems come from food, dietary modifications are an important solution. When they are believed to be the result of a shampoo, bathe the pet and look for a new product.

Fleas are the cause of both delayed and immediate responses. Itching occurs soon after being bitten and can endure for as long as fleas continue to exist. Flea control is a great solution to this problem and other pets in addition to the one effected must be treated. This lowers chances of recurring problems. Antihistamines can reduce itching and medicated baths and antibiotics are commonly prescribed cures.

Dog skin allergies are increasingly popular. They occur due to foods, airborne substances, or anything an animal comes into physical contact with. Symptoms may take place almost immediately or be somewhat delayed, appearing days later. Flea allergies cause both of these reaction types.
