Billi would bite at her slicker brush when she was younger and still runs from it when I get to her tooshie and hind legs... She's about 5ish months, so I think it has more to do with her puppy coat being difficult- I'd imagine that's what's bothering your lil boy!

I've heard shaving their puppy coats off can help; it could also be that he needs to have his hair kept short, too. Give him some some time & lots of treats- it'll get better!
