I wouldn't really risk letting mine off leash on walks or any where where I think harm could come to them.
They do know "come" and will do it very well when they are in their training classes or at the dog park. I can let go of their leashes when we are within a couple of houses away on the way back from walkies and they will stay right by me or run to the front door. But I will not do even that all the time.
For me, it is just too much of a risk --- there are cars, hawks, dog nappers and other evils out there. They can run around in the back yard unleashed. |
