Hi Ronnie, I wanted to let you know how well the boots work. Our almost 11 yr old German Shepherd was having so much trouble just getting up, could sit, and difficulty walking on our tile/wood floors. Her back end would collapse and many times she would be in pain. Since we purchased your summer boots she has been like a young dog again, being more active and playful in the house and not show any signs of being in pain. The rubber soles are fantastic! We purchased all 4 boots but we started with the rear only. She didn’t take long at all to get use to them and she doesn’t mind getting them put on now. Next will be the fronts. Thanks!!! Alana
