My dog has a red bump on her lip that's growing. Is it serious?
Thank you for using Petco Pet Education Center, formerly Petcoach! Kona does have what appears to be a small, round, red and slightly bloody bump on her lip margin. This can be caused by an infection, which may have resulted from a small cut. While Kona is pretty young, it is possible that the bump is a small tumor, and it can be removed to determine if it is benign (not harmful) or malignant (likely to spread). It is concerning that the bump has gotten bigger over time, so I recommend having her seen by a vet. You can get her an E-collar or "cone" to prevent her from scratching or rubbing the area. I hope this helps!
