1.) We live on a VERY busy street

. Do Yorkied run if a door is opened? What changes,(besides moving,) can we make to prevent this from ever happening
i guess it depends but I have never had trouble....gracie wants to stay right next to me....you just have to be very careful with the front door!!! and make sure she is always on a leash when outside
2.) My sister is 5 years old, Do yorkies do well with children? She is very gentle and will not be rough.
My experiences with Gracie and kids have been wonderful!!! She is very gentle, and patient with them...she would bite a little at first but just puppy bites nothing vicious
3.) Does anyone know about how much it costs to put a fence in? We are going to need one in our back yard.
not a clue....
4.) How do we go about finding a responsible breeder?
just ask LOTS of questions....talk to other people who have gone through breeders to find the best one
5.) At what age should we bring our new puppy home?
they say 12 weeks....but we got gracie at 8 weeks and she was fine
Thank You in advance for any answers... I look forward to talking with you guys!
