My goldendoodle occasionally throws out her back squirrel chasing and so I wanted to get some stairs to help her in and out of our tall beds. The stairs are a perfect size for her.  She weights approximately 65 lbs and is a very tall dog.  The only hesitation she has with the stairs is that her feet sometimes slip on the vinyl part of the stairs.  I might try to get some thicker carpet squares for the tops of the stairs to help with this issue.  Otherwise they work great!
