Shovel excrement officer takes a dog to vaccinate, after coming home, discover unexpectedly the place that the dog has an injection appears to shed hair, the circumstance that the hair changes color, how be to return a responsibility after all? Let Dr. E tell you about science.
Injection reaction
Due to individual differences, dogs will have some allergies after vaccination, which is very rare.
Hair loss at the injection site is also an adverse reaction to the vaccine, which we call injection reaction. It is mainly manifested as a focal, oval bald spot at a specific site after subcutaneous injection for a period of time. Some of them can also see the change of hair color. This phenomenon is more likely to occur after the injection of rabies vaccine, because rabies vaccine is an oily injection, which is not easy to absorb.
This condition is usually untreated, and the local coat regenerates naturally, but it can take up to a year. But if the hair follicle is damaged, no new hair will grow behind it.
Solution
Vaccination can choose the dog's inner thigh and other inconspicuous positions for vaccination. Antibody testing can be done before vaccination every year. If the dog's antibody level is high, there is no need to vaccinate.
Dogs that have lost their hair due to vaccination can choose to feed hair-beautifying powder, such as seaweed powder, to promote the growth of their hair.
