My dog's jaw is swollen with a lump. Vet says infection, what to do?

Updated On September 23rd, 2025

Pet's info: Dog | Black and Tan Coonhound | Female | unspayed | 11 months and 8 days old | 49 lbs

My dog has a huge solid ball in her lower left jaw and recently her face started to swell on the same side i took her to the vet but the vet said it is just an infection. She has had this before and it went away with benadryl but last time it was her snout and throat.. What do i do? I don't want my dog to suffer any pain..

It sounds like this swelling could be an infection, which could be caused by a dental problem or an abscess, among other causes. What you are describing from before sounds like an allergic reaction, which can be treated with antihistamines. Allergies would typically cause symmetrical swelling, not just on one side, which is why I'm lead to believe she has an infection. Because I can't see Sophia in person, I can't say for certain that it's an infection, but I would recommend listening to your vet who has seen her in person.
