My dog's face is swollen after vaccine. Is it serious? What to do?

Updated On September 23rd, 2025

My dogs face is swelling after a vaccination he got today. Is this dangerous or what can we do to help him? Some of the side effects were facial swelling but I’m not sure if that’s dangerous or not.

It is only dangerous if the swelling is causing her to have difficulty breathing. Getting her to a vet is the best option but if you want to try something at home you can give Benadryl by mouth at 1mg per pound of body weight (example, if she is 25 pounds, she would get 25 mg). Always let the vet know when she is vaccinated in the future that she had a previous reaction.
