I can not understand why even until my third dog, which is now already 5 years old, the idea came to buy a pet stairs. Specifically, this staircase is robust and has just the right weight so as not to slip if my dog up the stairs nutzt.Der reference is impervious but removable and washable. Especially with short-legged dogs you should definitely buy something at the back and protect the spinal discs. And with a few treats is your favorite understand very quickly what the stairs are there and they will eventually be used as a matter of course, because he realizes what a relief that is.
