I couldn't find a specific link but I have a crate from Petco. It's called the Dog Whisperer and it's the smallest one they carry. My doggy was about 3lbs but this was definitely big for him. I'm glad I didn't get anything smaller though as he will grow into it. - Oh and he has never soiled it at all OR b/c of it being too big.
What I did to keep him all cozy is I layered it with a wooly kind of crate layer and then I put in one of those puppy stuffed animals - the ones with the beating heart and warmer - didn't use the warmer though but turned the heart on. And I then rubbed a little puppy blankie on me and put it in there. It worked out great but he didn't like the car much as he never had had a car ride or had been outside, day or night, so he freaked about that. But his crate became his comfy abode from day 1.
Hope this helps.
