Well Slinky in the film Toy Story 1& 2 was a dachshund of course, and the following site claims that you can buy him:

But I’m not convinced it’s really Slinky. I think he’s an imposter! The eyes, eyebrows, legs and tail are different. Maybe there were copyright issues, but then again, they still called it Slinky Dog.
And who on earth would attach the leash to the poor little thing's FACE? For heaven’s sake!
