Yep ... I had some just like these but they never got used, so I dontated them to the RSPCA .... they are made of plastic & very light weight, but sturdy enough ... Harley is over 10 lbs & they would stand up to him ...
Plush Doggy Steps 30.5cm x 35.5cm x 46cm - Dog Supplies
Thats what Nelson has and uses just fine. They were hand me downs from Andy. Andy could go up them, but he usually ended up just jumping down over them instead, so we took them down.
But then we bought a 2nd set for our cabin. Other than he likes to chew on it they are great! 20 bucks at Target, I dunno if you have one of them there?
