My female bp Bella is a little over a year old, and yesterday I was giving her a bath and noticed that her mouth's kinda swelled up on one side on the inside. I immediately thought "mouth rot", but I haven't found any discharge, blisters, or discoloration, and she's not wheezing. I don't know what else to look for without taking her to the vet, but I can't really afford to take her until next week, but if its something serious, I don't won't to make it worse by waiting either. Any suggestions?
