Allergic reactions to general vaccines are not very rare

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

We know that no matter how big or small the dog is, the dosage of vaccinations for them 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 types of dogs, and their body weights vary greatly. Unlike common drugs, the immune response caused by vaccines and body weight are not linearly related, so there is no way to distinguish different dogs with different body weights. Dosage to break out is enough for maintenance. So to put it simply, small dogs often need to receive excessive doses of vaccines. Therefore, safety testing of vaccines is very important.

Currently known factors from vaccines include:

Vaccine antibodies, vaccine adjuvant Residues produced by the organization during the production process of agents, vaccine protectants, vaccine stabilizers, and vaccines.

Based on the fact that these factors do not seem to change much in the near future, we might as well pay attention to which dogs are more likely to develop allergies, and at the same time It is also necessary to understand what measures can be taken to alleviate symptoms after adverse reactions to vaccines occur.

Factors likely to be related to adverse vaccine reactions:

1. Dog’s body weight

A survey has shown that the incidence rate of adverse vaccine reactions in dogs less than 5 kg is 0.45%. The incidence rate of adverse vaccine reactions for dogs weighing more than 45 kilograms is 0.1%. The vaccine response rate for dogs under 10 kg is better than that for dogs over 10 kgMore than twice as much as dogs. Therefore, dogs that are underweight may be more susceptible to adverse reactions.

Pay more attention to smaller dogs

2. Reasons for dog breeds

Ordered by the incidence of adverse vaccine reactions, the highest one is Sausage dogs, followed by pugs, Boston terriers, fawn dogs, Chihuahuas, Maltese dogs, miniature schnauzers, Jack Russell terriers, toy dogs, Yorkshire terriers, boxers, and American dogs (certain introduction ), Pekingese dogs, lion dogs, and English bulldogs, etc. The vaccine reaction incidence rates of these breeds range from 1.21% to 0.42%, which is much higher than the 0.13% for giant dogs, such as German Shepherds.

3. Whether the dog has been neutered or not

Neutered dog Dogs may be more susceptible to adverse reactions than unneutered dogs, which may be related to adverse reactions related to sex hormone-attenuating vaccines.

Relevant treatment methods after the dog has adverse reactions:

1. Rare: the combined use of antihistamines and glucocorticoids; the independent use of antihistamines or glucocorticoids. Some dogs have adverse reactions that will show up through the skin, and general injection of chlorpheniramine will cause acute relief.

2. If the situation is serious: infusion, oxygen infusion, diuretics, non-steroidal anti-inflammatory drugs, and adrenal hormones can be used.

Immunization still requires the full dose to ensure the protective nature of the vaccine. For dogs that are small or underweight, we need to pay more attention to their condition. . Some owners are afraid that there will be too many bacteria in the hospital, so they take their dogs home just 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 relevant adverse reactions. If not, you can send the dog home..
