I have a 10 lb dog (a Maltese) and he's getting older. I also just got a new bed that sits 24 inches from the ground. He can jump down without problem/hesitation, but has a hard time jumping up onto the bed. I've been researching dog steps and the one set I found on petco's site that's tall enough ends up being $40. Does anyone know of a less expensive but sturdy set that's tall enough? Or does anyone know how one might go about making a set (not even sure that'd be cheaper after time and materials)? any other ideas that I'm missing?
