Has anyone seen a pink spot on lip like like this? Just noticed it and while we are watching it everyday since we noticed it, it is not changing or getting bigger. Has anyone else been to the vet for something like this? Curious as to what it could be. He does not seem to notice it there, and it is not an open wound. It is also flat, no bump there. see pic

Looks more like some spot that he may have cut a long time ago. I wouldn't worry too much about it. Doesn't look like some kind of active wound or surface bacteria. It's not up in his fur area around his lip that would suggest a zinc deficiency. Sometimes they just bite their lip eating or something or cut it on grass outside and the fresh skin comes back unpigmented. Not a big deal.
