Reasons for low dog immunity:

1. Lack of nutrients in the feed

If the dog feed lacks vitamins, amino acids or minerals, etc. Nutrients will cause the dog’s immune organ function to decrease and immunity to decrease. Preventive Measures: When an owner feeds his dog, the feed should be fully matched according to the dog's physical needs. The nutrition must be sufficient and comprehensive. Don't stop feeding the dog just because he doesn't like to eat.
2. Chronic poisoning of dogs

Because too much sodium ions will suppress the immune system, immunity will gradually decline. . Preventive measures include: the amount of salt used in the dog's feed must meet the requirements, and the dog cannot be fed random human food.

3. Insufficient exercise
The amount of dog exercise also has an impact on the dog’s immunity. Through exercise, it promotes blood circulation in the dog’s body, accelerates metabolism, enhances the dog’s physical fitness, and improves the dog’s resistance. Strength and immunity, so a dog that likes to exercise will have a much higher immunity. Therefore, it is usually recommended that owners take their dogs out to exercise more to absorb more minerals and trace elements.
4. Abuse of antibiotics
This is an obvious problem. The abuse of biological agents is the second most common problem, and the abuse of glucocorticoids is the third most common problem. These drugs can seriously affect the immune function of animals, and long-term abuse can easily cause low immunity in animals.

5. Changes in the environment

If a dog suddenly enters an unfamiliar environment, it will have a corresponding stress response, and at this time the dog's own immunity will also decrease accordingly. , so generally speaking, when the dog has not adapted to the new environment, owners should not take the dog out easily, bathe, or vaccinate, otherwise it will be very harmful to the dog.
