My husband bought my daughter's dog from what I later found out to be a puppy mill.
He was supposedly a Pom, but the vet said he looked more like a long-haired Chi. He was so sick and debilitated when we first got him, it was hard to tell.
Now that he's healthy ( and a whopping 3 pounds at l year old), the vet says he's more than likely a Pom-Chi mix. Not what we paid for, but he is the dearest little man.
