Not sure this is the right place for this, but I'll give it a shot. My dog is Lab/Border Collie mix and very very driven and focused when given a 'job' to do. I want to look into training for flyball or agility or stuff like that, because I think he'd really like it. I've also started having him walk with a backpack (unweighted for now) which the trainer said will help when he's older. What sort of activities help your dogs feel like they have a job or that feed that strong drive to work?
