There are not many examples of vaccine allergy

Relatively speaking, it is relatively rare for dogs to have allergic reactions after vaccination. After all, vaccines need to go through a lot of testing before being put on the market. However, due to individual factors, some dogs will still experience related adverse reactions. Generally speaking, these allergic reactions are not fatal, but they must be dealt with as soon as possible, otherwise they will still be dangerous.

Small dogs usually receive an overdose of vaccines

We know that regardless of the size of the dog, the dose of vaccination is the same. Therefore, for some smaller pet dogs, the amount of vaccine may be slightly excessive, but it will not cause any harm to them. There are too many breeds of dogs, and their weights vary greatly. The immune response caused by vaccines and body weight are not linearly related to general drugs, so there is no way to give different doses to dogs of different weights to produce sufficient protection. So to put it simply, small dogs often need to receive an overdose of vaccines. So safety testing of vaccines is important.

The factors currently known to come from vaccines include

vaccine antigens, vaccine adjuvants, vaccine protectants, vaccine stabilizers, and tissue culture residues during the vaccine production process.

Given that these factors don't seem to change much over a short period of time, we can focus on which dogs are more susceptible to allergies and also learn what methods can reduce symptoms after an adverse reaction to a vaccine.

Factors that may be associated with adverse vaccine reactions

1. Dog weight

A survey has shown that the incidence of adverse vaccine reactions in dogs less than 5 kg It is 0.45%, while the incidence of adverse vaccine reactions in dogs over 45 kg is 0.1%. The vaccine reaction rate for dogs under 10 kg is more than twice that of dogs over 10 kg. Therefore, dogs that are too small may be more susceptible to adverse reactions.

2. Reasons for dog breeds

In order of the incidence of adverse vaccine reactions, the highest rate is Dachshund, followed by Pug, Boston Terrier, Fawn, Chihuahua, and Maltese. Dogs, Miniature Schnauzers, Jack Russell Terriers, Toy Poodles, Yorkshire Terriers, Boxers, Pomeranians (details), Pekingese, Lion Dogs, and English Bulldogs, etc. The incidence of vaccine reactions in these breeds ranges from 1.21% to 0.42%, which is still much higher than that of large dogs, such as German Shepherds, which is 0.13%.

3. Have you been neutered?

Neutered dogs may be more susceptible to adverse reactions than un-neutered dogs. This may be due to sex hormones attenuating vaccine-related adverse reactions.

Relevant treatment methods after adverse reactions in dogs

1. Common: combination of antihistamines and glucocorticoids; one-time use of antihistamines or Glucocorticoids.Some dogs have adverse reactions that occur through the skin and are generally relieved by chlorpheniramine injection.

2. If the situation is serious: infusion, oxygen infusion, diuretics, non-steroidal anti-inflammatory drugs, and adrenal hormones can be used.
Immunization still requires injecting the entire dose to ensure the protection of the vaccine. For small or light dogs, more attention should be paid to their status. Some owners are afraid that there will be too many bacteria in the hospital, so they take their dogs home right after the injection. However, for the safety of the dog, wait about 10 minutes after the vaccine injection to see if the dog has any related adverse reactions. If not, the dog can be sent home.
