I too live in England and I think what people look for in a Yorkie differ over here.Most Yorkies you see over here are on the larger side,well they are around where I live.I had 2 Yokies years ago and they both weighed over 10 pounds.My last yorkie,Trixie was small boned and weighed 7 pounds.People used to think that she was small.I now have Ellie who is 5 months old and weighs 3 1/2 pounds, people ask me if she is a miniture or a tea cup

I tell them no shes just a Yorkie.People here are just not used to seeing tiny dogs.Big babies or little babies,all mine were and are loved for what they brought into my life.Fun,personality and unconditional love.
Be they large or small,Ilove them all
