[I am spoiled]

I recently purchased a set from doggysteps.com. It is a 3 step, however, you can purchase a kit to make a 4th step. My yorkie just uses them getting on and off of the sofa, so the 3rd step works for him. It cost me about $25, however, I saw some yesterday at Walgreens for $10. They are basically the same. They both hold up to 70 lbs. The training wasn't that hard either. I just placed treats on the steps and he went up and down them. Show him how it is done first by walking him up them. I recommend that every small dog have a set.
