We have a 15 (almost 16) year old Chihuahua named CoCo. She has hip issues & just general aging problems getting around, putting in hardwood floors didn’t help her situation in the least. I saw your product on FB and decided to give it a try, I am SO happy that I did!!!! She is such a happy girl and is more active than she has been for months!!! Great product, thank you PawFriction!!!!!
