Well I really didn't want to get too into that b/c of some opinions on here. I get so much conflicting info its hard to pick what is best. Basically he is still biting from puppyhood, but it isn't agressive, just attention getting and dominance problems I think.
Everytime he bites yell ouch and shove a toy in his mouth. it worked for cc, It's kinda funny, if you come into my house CC runs and gets a toy, so you know that shes not gonna bite you. It's worth a try anyhow
