I lent my Bible Water Dog out and am looking for advise/tips. I have a Lab that will be 2 years 4 months at the start of this, his 3 year hunting. He's a pleaser and an intense hunter and I'm already looking forward to this years hunts!

I'm looking for ideas for games besides baseball that the dog will like and at the same time retrain/strengthen his trust in me giving him hand signals.
