My brother is in our bubble and our dog absolutely loves him. The dog is 16 months and very friendly. But he jumps up, tries to lick my brother's face and then bites/chews his hands. We've tried exchanging this for toys but it makes him more hyper.
Today I basically kept him on the lead or in his crate because he was being so stupid. So I really need to address this. Any advice would be appreciated.
