Q. I had taken my 3 month old pug dog for vaccination doctor had injected , but now the injected sport is been swelling , in round shape as a ball kindly

A. Pain, swelling, redness, and irritation can occur at the injection site. These effects generally occur within 30 minutes to 1 week of the vaccination. If the signs persist, or are severe, I would recommend to contact and take him back to your veterinarian.
Occasionally, abscesses can form at the injection site. These abscesses are generally not caused by infection, but by the body's over-reaction to the vaccine.
