Hi all my 18 month old GSD has lost the colour on one side of his bottom lip(gone pink).The vet has done a biopsy but the results dont help him he seems at a loss.Anyone got any ideas thanks

I wouldn't worry as it is just pigment loss. My Lab Moose has this on her nose and on her lips but has improved with a  supplement with elder berry extract in it. Also sea kelp supplements are supposed to be good. It maybe a concern if you are showing but if not, I doubt it should be anything to worry about.
