Sure Stay is one of our personal inventions we made for our dog Simba to use when she has to go outside and potty. Fear not she does not stay on it all the time it is just for when she uses the potty.
She pulled the track of our garage when I tied her to it after trying multitudes of tie outs for her she would still get loose or tangled so we made this for her. She is a wonderfulr blonde lab about 77 years old in dog years now and does not walk with us as much as she used to. This video is of one of her friends who is in a lot better shape.
