Causes of dog allergies

The antigens that cause allergic reactions in dogs are called allergens. Allergens are necessary for allergies to occur. There are 2,000-3,000 antigens that cause allergic reactions, and nearly 20,000 have been recorded in medical literature. They cause allergies by inhalation, inhalation, injection, or contact. Common allergens are as follows:

1. Inhaled allergens: such as pollen, catkins, dust, mites, animal dander, oil, paint, car exhaust, gas, cigarettes, etc.

2. Ingestible allergens: such as milk, eggs, fish and shrimp, beef and mutton, seafood, animal fat, foreign proteins, alcohol, drugs, antibiotics, anti-inflammatory drugs, sesame oil, flavors, onions, ginger, garlic and some Vegetables, fruits, etc.

3. Contact allergens: such as cold air, hot air, ultraviolet rays, radiation, cosmetics, shampoo, dish soap, hair dye, soap, chemical fiber supplies, plastics, metal jewelry (watches, necklaces, rings, earrings) ), bacteria, mold, viruses, parasites, etc.

4. Injection of allergens: penicillin, streptomycin, heterologous serum, etc. Penicillin is the first drug to cause allergic reactions in dogs and cats; other drugs are sulfonamides, griseofulvin, cytosine, and sulfamethoxazole. For example: surface exfoliation caused by quinidine; bullae caused by phenytoin; purpura caused by chloramphenicol; urticaria caused by tetracycline; fixed drug eruption caused by ampicillin, etc.

5. Self-tissue antigens: self-tissue antigens whose structure or composition changes due to mental stress, work pressure, microbial infection, ionizing radiation, burns and other biological and physical and chemical factors.

Clinical symptoms of dog allergy

a), food allergy:

Make a diagnosis based on medical history and clinical symptoms. In addition, feeding the suspected food can be stopped for diagnosis.

1. Skin-type food allergy. Dogs usually experience systemic itching after eating, or erythema, papules and scales on the skin all over the body, hair loss, epidermis peeling or ulcers, urticaria and angioedema, pustules and otitis-like symptoms. .

2. Gastrointestinal symptoms, mainly watery diarrhea and vomiting after eating, mild intestinal inflammation, severe hemorrhagic colitis, and bloody stools.

3. The gastrointestinal type and cutaneous type sometimes occur at the same time, but most are single types.

b), drug allergy:

Diagnosis can usually be made through medical history investigation and reference to clinical symptoms. Diagnosis can also be made with drug withdrawal or drug provocation.

1. Since there are many causes of drug and vaccine allergies, their clinical manifestations are different, and specific symptoms are usually not obvious.

2. Its common skin symptoms include papules, pustules and bullae, bleeding, erosion, ulcers, scales and scabs, etc.
