Dog vaccine allergies are divided into acute allergies and chronic allergies. Acute allergies will cause swelling of the face and mouth, and in severe cases, convulsions, death, etc. The dog must be given a desensitization injection immediately for treatment. Chronic allergies generally resolve within 12 to 48 hours. During this period, you may experience poor appetite, drowsiness, and good mental status. Desensitization is usually not recommended for chronic allergies because desensitization shots will affect the production of antibodies to the vaccine. The current vaccine allergy rate is relatively low, about one in a thousand, so don’t be nervous. For the health of your dog, you must get vaccinated in time. Prevention is better than cure.

The reasons why dogs are allergic to vaccines:

1. Dogs are allergic: Before injecting vaccines into dogs, a health examination must be carried out.

2. The dog’s mental state is not good: you can wait until the dog calms down before giving the injection.

3. There is a latent virus infection in the dog’s body: targeted treatment first, and then vaccination after the dog’s body recovers.

4. There is a problem with the vaccine: Choose a vaccine that has a national approval number, has vaccine business qualifications for sales, and has a 2-8°C cold chain guarantee.
