Amazon.com: Midwest 1524 iCrate Single-Door Pet... I use that same crate for all my Yorkies. I like it cause they can be folded flat and stored in a closet too.
I like the plastic ones to transport to the Vet. I was so happy when I found two at a yard sale for $3 each. A good scrub with bleach and hot soapy water then rinse really well.
