We bought this ramp after a minor injury our little dog had so that it would tire her leg as little as possible.
No matter how hard we tried to teach her to use it, we failed, and unfortunately, this is because the step on the ramp's stairs is small compared to the height from one step to the other, which is large.
Unfortunately, while the construction is generally good, due to its poor design, it does not serve its purpose, especially when we are talking about small and short-legged dogs.

Excellent, wonderful color, good quality plastic and the adhesive pads are very soft! But guys, you have gone overboard with the prices for pet products!! (And I don't mean skroutz)
