Ulcers on the lips usually indicate an infection. That may be related to how the tooth touches the lip in that area. You need to have your vet look at the lip to see if the teeth need cleaning or the dog needs an antibiotic to treat this type of infection.

Reply to dr4pets's Post: could this be something other than an infection? IS there anything that I could do to avoid the vet visit?
Expert:  Dr. Louis Gotthelf replied 11 years ago.
Without seeing the lesion, I cannot tell you anything very specific. Is this on the inside of the lip or the outside?

Reply to dr4pets's Post: on the outside of her lip and it appears white in color

OK. Try and describe it to me. Is it like a blister with fluid in it? Is it white like crusty? Is it thick and hard? Is it painful?

Reply to dr4pets's Post: it looks clear to me. it is not at all painful to the touch. it is directly below her nose. where the right nostril and the lip meet. there is not crust and it doesn't ooze even if I apply pressure

Is the pigment gone and is it pink where it should be black?

Ok, now we are getting somewhere. There is probably not much you can do except to put a steroid creme on it. If you want to go through having a biopsy, that is possible. There are a couple of autoimmune diseases that cause depigmentation; pemphigus and discoid lupus.
