The Fido Fleece sweaters are great! That's what Nakai has (see post above). They do cover most everything. I like that they cover the hips better than some other sweaters, especially in larger dogs who are prone to hip dysplasia.
Nakai has learned to raise each paw as we put the sweater on him. He doesn't mind having it on while he's outside, but when he comes in, if you don't catch him right away, he starts rubbing on the couch like a cat to get it off! 
We have also used it on him while camping, if he begins to shiver in the night. At that point he actually loves having it on, and it moves with him so you don't have to worry about replacing it when he changes position like a blanket.
