4.5 month old puppy has thinning hair on the face
My 4 and half month old girl has a thinning hair on the bridge of her nose. I haven't seen her scratch it and it does not look red or scaly. She has two hair-thinned out spots on her head too, one which I know happened whilst she was playing. The hair around her eyes also look a little thinned out for my liking. Her trainer ( he has two GSD's as well) mentioned to me that it is normal for a pup since his went through the same thing. She is on salmon oil, calcium and multi vitamins with a good quality kibble.
I am taking her to the vet tomorrow for a check-up to make sure she doesn't have mange, but is this normal?
