The Sugar Baby back blip

Sugar is always tethered. She is 6 years old and still pulls on a leash when she wants to go. I've never seen anything like it. She is the first dog we have had to do this. Today we got brave and let her run loose in the yard on the farm, toys and treats in hand. She did well but we know she is not one to be trusted. She tries to run everything from a butterfly to a helicopter. She had a grand time but ran to the door when she was ready to go in. We will give it a try again for sure.
