Bulldogs World

Morning everyone - hope you all had a wonderful Halloween! Question for all you bulldog lovers - Bosco's pigmentation seems to be changing. What once were small black freckles on his face and along his jawline are bigger and the coloring in his mouth is correspondingly changing, as well. I flagged one freckle for his vet the last time he was in for a wellness exam because one freckle in his mouth was looking different and the vet said it was no big deal. But given the broader pigmentation change, just wanted to get opionions from you all before I bring him back to his dermatologist. Welcome your thoughts and thank you!
