Must be difficult. I imagine the young one is frisky while Bruce has calmed down.
I'm guessing as I've never had a dog.
Aye. Bruce has always been a calm character and was easy to train. Geddy is like a Tasmanian Devil on acid, but he will learn. He already knows the drill and verbal commands for crossing the road.
But the bigger problem is Geddy is still shy of 5 months old and I have to limit his exercise or risk affecting his skeletal development, yet I also have to walk Bruce who is an athlete in his prime.
So today I compromised, taking Geddy along for a distance probably a bjt beyond that which is advised for his age but doing so at a slow pace, and then keeping him on the lead while Bruce gets his 30 throws of the ball. 25-30 is his limit before hes honking in his effort to breathe - I wind that back or even do away with the ball entirely if its too warm, and he's at his peak now so over coming years ill gently reduce the number of ball throws.
Another bonus is that Geddy absolutely adores his adopted big Brother and falls into step alongside him so he isn't pulling too badly.
