My two little dogs use their new steps and get on with them well. My older dog has Arthritis of the spine so it helps her get on an off our bed. The tread area is non slip which is good but the tread area should be a little wider in my opinion. That’s why I didn’t give 5 Stars. Also I wouldn’t feel happy to let a bigger dog use them because although they are sturdy I don’t think a dog larger than a 12Ib would be safe. Reasonable price as well.
