I have one just under 3 pounds and one that is 5 pounds. The vet says they are both healthy as can be. Neither has ever had hypoglycemia or any other health concern. They are very, very active and rule the house (including all 3 humans, a Jack Russell and a Dachshund). Both came from reputable breeders, have good pedigrees, with good health histories on all sides.
I think Sadie (5 lbs) is sturdier than Ben but stepping on either one of them could be horribly dangerous. Actually, I think stepping on my 11 or 13 pound non-Yorkie dogs could be horribly dangerous too.
More important than the exact size is to make sure you are using a breeder that knows and cares to do it right. Look at the pedigrees and ask about the health of parents and grandparents. Look at the conditions the puppy was raised in. Look hard at the puppy -- clear eyes, good joints and bone structure; no crusties, coughing or listlessness. The puppy should look interested, curious, friendly, and happy to be around people. Some might be a little shy at first so give them time to be comfortable around you. But don't pick a puppy who just sits and looks unhealthy. Don't pick one that looks too skinny, or undernourished. (Unless you want to rescue them, that is.) JMHO. |
