i had the same worry with Remy! i thought he started balding at about 4 months at the top of his head, but people say its normal for some dogs and it could be his hair turning lighter so it looks thinning out. i had a thread about it a few months back about him balding. i asked my vet and she said i had nothing to worry about it. Remy's face has turned really lighter than the rest of his body, but i assume thats normal as well.
but check w/your vet and see if they have any ideas why. dont worry though, maybe your furbaby is just stressing out!
