Query: Post Surgery

We bought these steps to help our Malti-Poo get on the bed after having knee surgery on both knees. It took some coaxing (treats)to get him to go up, but he healed and is still using the steps. Now, he loves to run up them and jump on our other dog. We bought a second set so he could get into his favorite lounger, too. These are solid and the stair treads make him feel secure. I don't regret my purchase, and would gladly buy them again, if needed.9/15/08 These steps are still like new, and he uses them every day. Also keeps him from messing up his back by jumping off the bed.
