Bell is a prue breed, I don't know why she got so big, But she did... When this breed was first around they were bigger dogs, ( not huge, just bigger ) they were used to hunt down rats, So maybe its that or improper breeing, Who knows for sure.. Most people only see the mother, and who knows what or who the father might be!! In my case I saw the father (at least they told me so) and he was smaller. But Bell being my first yorkie and thinking back I think her mother was larger.. But I was so excited in getting a new baby I wasn't being very choosey!!
