Pet's info: Dog | Mixed Breed Small (up to 22lb) | Female | spayed | 21 lbs
Hi! We were on vacation for a week and left our dog Lucy with our in-laws for the week. We just picked her up and noticed a small blister like bubble on her mouth. It doesn't seem to hurt her, and she's plenty playful otherwise. Any thoughts?

Hi there and thanks for using Petco Pet Education Center, formerly Petcoach! It's hard to tell for sure from the picture but that small area does not look like a major concern to me. It is near impossible to diagnose a growth on just a picture alone so it's probably a good idea to have a veterinarian check out the bump area within the next few weeks (especially if it changes in size, shape or color). A veterinarian will be able to take a needle aspirate of the area and see what kind of cells are there to determine if anything needs to be done about the bump. At minimum I would closely monitor the area and if the shape, size or color changes, take Lucy to be examined. Regards to you and Lucy!
