When Rufus is inside the house he behaves, doesn't pick up things.
When we are outside I walk them both on the leash and from the beginning I trained both to walk besides me.
I only let them loose when we are at the park and when no other dogs are around.
When I let him run in the park, that's when the problem starts.
I think it's when he gets exited and then he starts picking up stuff (while running) |
