Any ideas how I can play with my 8 month Yorkie outside without a leash or a fence?
It's cooling off here and I would love to play with Ruger outside, chase, fetch,run together, etc.
The problem is: play is limited on a leash. I'm afraid if off leash he will go off chasing birds, butterflies, anything that moves. And he can run as fast as Superman.
He's been leash trained since 11 weeks. Does very well, but I'm in control.
Really want to have some fun outside.
Thanks
