Max is 7.5 months old now and is going through his autumn-winter shed. Ive been brushing him everyday and manage to get a good amount out, most of it from his scruff and mid-back. He started out moulting with darker patches on his head then back which looked a bit concerning at first. Today, i took out a good tangled bit on his back and when i moved the fur around, I could see his skin quite a lot. It has never been this thin to the point where I could see his skin before, and it's only on this one spot that is like this. Is this normal or is he losing fur from mites or something else?
