On Thursday night, my 11 year old chow's lower front gums became swollen and grayish colored. For a couple days prior, she'd been licking her paws a lot, and we think maybe that caused some bacteria to get into her mouth. Only the lower front part is affected, and she doesn't seem to experience any pain chewing. Her appetite hasn't changed at all, although she does seem slightly more lethargic than usual (but it's hard to tell because of the heat wave we're currently experiencing.) The only noticeable symptom is bad breath.
We already called the vet, but the earliest appointment we could get was for Monday. The receptionist said that since she was acting normally, it probably wasn't that serious. We even called a couple other animal hospitals that our friends have experience with to see if we could get an earlier appointment there, but weekends are full.
Should I take her in for emergency care, or to an unfamiliar animal hospital that accepts walk-ins/same day appointments, or just wait it out until Monday?
