Hello everyone. I’m new to the community so I hope I’ve done this right! Bruno is about 6 months old and over the past week I’ve noticed a grey mark/lump on his face and nose. I’ve tried researching online but I can’t find anything similar! I can’t tell if it is a lump or scab or just his fur as he has been changing to a lighter colour with the warmer weather. I have attached a picture. Does anyone know what this is or if you’ve seen it before? His behaviour is completely normal and I’ve noticed he is still grooming his face so I don’t think it is hurting him and he’s not itching either. Do you think we need to see a vet? Thanks in advance!
