Shyloh is pooping right at my back door on the concrete. I have grass all over the place and as we are out there. She goes right back to the door! She is so fast, by the time I get to her she has already gone. I am disabled and walk with a limp. I am slow. I can't catch her. I walk her to the grass and she runs back to the door and poops. I am so frustated. Bella goes in the grass. I have spayed dog repellant, no help! Just not sure what to try with this stubborn little girl! She a tough one!
