haha. thats funny. I had the same exact problem with Boots. He, too, has all the chewing toys you can imagine yet he'd always go after me... what I noticed is that he is bothered by "good" scents... as I was applying lotion one day he began barking at my legs.ha.
so one day that he began biting/chewing on me... I applied lotion (Jergens cherry-almond original scent) AND HE STOPPED. he tried to bite/chew on my feet, applied some lotion, and HE STOPPED!!
