Have you notice any shaving cream near your dog's bed?

Is he losing hair anywhere else? How old is he? Is he eating/drinking normally?

Once in awhile, we find a cat whisker. They shed them once in awhile, but not all at once.

Maybe he's just getting older and is experiencing dog-pattern baldness?
