Dogs and cats sometimes suddenly experience sneezing, itching, trembling, etc. If there are no other reasons, the probability of allergic reactions is higher. In medicine, antigenic substances that induce allergic disease outbreaks are often called allergens. Since there are thousands of species, each dog and cat allergy is likely to be caused by a different antigenic substance.

Allergic reaction:

Some pets will develop abdominal pain, diarrhea, vomiting, or itchy skin after eating fish, shrimp, crab, etc.; some will develop rhinitis or asthma after inhaling pollen or dust; some will develop rhinitis or asthma after being injected with penicillin. Shock occurs. These are all symptoms of allergic reactions. Severe allergic reactions can also lead to death.

Allergic reaction refers to a reaction of tissue damage or dysfunction that occurs when an immune body is stimulated by the same antigen again. The reaction is characterized by rapid onset, strong reaction, and rapid subsidence; it generally does not destroy tissue cells or cause serious tissue damage. It has obvious genetic tendencies and individual differences.

Common allergens:

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

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

3. Antigenic substances that cause allergies through touch - contact allergens: such as hair dyes, paints, cold air, hot air, ultraviolet rays, radiation, shampoo, dish soap, soap, chemical fiber supplies, plastics, metals Erection, bacteria, mold, viruses, parasites, etc.

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

Special reminder: If you find that your pet has an allergic reaction, you can do some simple desensitization treatments, such as taking medicine or injections and other symptomatic treatments. Serious and complex cases need to be sent for examination and treatment in time. However, there are many clinical symptoms that cannot determine the specific allergen at all, which is quite complicated.
