Here's a website I found:
http://www.petstep.com/
And I've seen them in pet stores too, like Petsmart. They seem to be pretty pricey though.
When we used to have a bigger dog (she's in Doggy Heaven now) my hubby improvised with a wide piece lumber and covered in with a bath rug so she wouldn't slip. It worked really well so if you're crafty or handy in that way, that might suit your needs.
