OK, thanks, Flakes (Post #70, my 'quote' feature isn't working). You appear to be right about labs. I googled dog bites and found out that experts rank dog bites in two different ways. 1, Human fatalities, of which pits and rottweilers are responsible for more than half the total; 2, non-fatal bites, of which a more wide range of dogs, including labs, are involved. The interesting thing is there are about 15-20 human fatalities a year in the U.S. from dog bites. But there are 5 million non-fatal bites a year. I won't draw any conclusions. Just wanted to pass along some information for fellow Yorkie owners.
Here are a couple interesting lists.
National study from 1979 through 1996 revealed that the following breeds had killed one or more persons:
Pit bulls, Rottweilers, German shepherds, huskies, Alaskan malamutes, Doberman pinschers, chows, Great Danes, St. Bernards and Akitas.

1998 study in Montgomery County Maryland listing the top ten biting breeds in Montgomery County in 1998. (This is a local study, but it's the best I could find.)

Chow Chows -- 9 major bites
Labrador Retrievers -- 9 major bites
German Shepherds -- 7 major bites
Pit Bulls -- 7 major bites
Akitas -- 5 major bites
Dalmatians -- 5 major bites
Rottweilers -- 5 major bites
Beagles -- 4 major bites
English Springer Spaniels -- 4 major bites
Collies -- 3 major bites
Jack Russell Terriers -- 3 major bites (tied for 10th)
