Climbing up the stairs is sometimes just not an option for canines on the older and rounder side. Currently a prototype, this doggie stairlift is designed with that problem in mind. A paw-print button near the base starts the unit; the dog then climbs into the basket, which lifts off the ground and travels the length of any staircase. In just a few moments, your dog is at the top of the stairs with minimal effort. Slated to retail at $8,000.
