Dogs and cats sometimes experience sudden sneezing, itching, tremors, etc. If there is no other reason, the probability of allergic reaction is high. In medicine, antigenic substances that induce allergic disease outbreaks are often referred to as allergens. Because of the thousands of species, each canine or cat allergy may be caused by a different antigenic substance.

Allergic reactions:

Some pets will suffer from fish, shrimp, crab and other foods after eating Abdominal pain, diarrhoea, vomiting, or itchy skin; some may experience rhinitis or asthma after inhaling pollen or dust; some may experience shock after penicillin injection. These are all manifestations of allergic reactions. Severe allergic reactions can also lead to death.

Allergic reaction refers to the tissue damage or dysfunctional reaction that occurs when the immune body is stimulated by the same antigen again. The characteristics of the reaction are rapid onset, strong reaction, and rapid regression; generally it does not destroy tissue cells, nor does it cause serious tissue damage, and there are obvious genetic predispositions and individual differences.

Common allergens:

1. Antigenic substances that cause allergies through breathing--inhalation allergens: such as pollen, catkins, dust, insect mites, cold air, animal skin Crumbs, oil fume, various spices, car exhaust, gas, cigarettes, etc.

2. Antigenic substances that cause allergies through diet - ingested allergens: such as seafood, fish and shrimp, allogeneic protein, dairy products, soy products, chicken and duck, beef and mutton, rice, flour, Sesame oil, toon, onion, ginger, garlic, animal fat, alcohol, and various fruits, dried fruits, vegetables, preserves such as peaches and pears.

3. Antigenic substances that cause allergies through touch--contact allergens: such as hair dye, paint, cold air, hot air, ultraviolet rays, radiation, shampoo, detergent, soap , chemical fiber supplies, plastic, metal ring, bacteria, mold, virus, parasite, etc.

4. Other allergens: such as injection of penicillin, xenogeneic serum, etc., mental stress, fright, etc.

Special reminder: If you find that your pet has allergic reactions, you can do Some simple desensitization treatments, such as symptomatic treatment such as taking medicine or injections. For severe and complex cases, timely examination and treatment are required. However, there are many clinical symptoms that cannot determine the specific allergen at all, which is more complicated.
