The swelling on a dog's neck after vaccination is mainly caused by malabsorption. First of all, injections that are likely to cause bulging in a dog’s neck mainly include rabies vaccines, because these vaccines themselves are not easily absorbed. Secondly, for the problem of bulging, it can be relieved by giving hot compress to the dog. If necessary, you can use drugs with ingredients such as Ichthyostatin. Finally, if the dog itself is prone to bulging when vaccinated, you can choose to vaccinate in the thigh area.

Notes on dog vaccination:

1. Do not change dog food, take medicine, change the environment, etc. immediately after vaccination to avoid stress reactions.

2. You must go to a regular animal hospital to get vaccinated by a professional veterinarian, so as to ensure the effectiveness of the vaccine.

3. Do not take a bath within 10 to 15 days after the dog is vaccinated, because the dog will be very weak after being vaccinated and its body resistance will decrease. Taking a bath at this time is easy to catch a cold and the wound will be damaged. Infections can occur from water.
