Thor walks on a leash (for his protection!) I wish he could play in the park with out a leash but he can be so unpredictalble and I don't want him to get gett his butt whooped by some other dog he starts stuff with. We are clicker training but I haven't done the 'come' thing with the clicker yet. Maybe some day he can be off of the leash in the park.
When he was a puppy I trusted him off of the leash, but one day something clicked and he "started exploring father away from me" (ie running away!
)
But he still LOVES his walks!
