how old do yorkies have to be to breed
Owners must be very aware of their Yorkie's bite during this age. 5 Months to 9 Months-It is during this time that a female Yorkie will generally enter her first heat. It is strongly recommended to have your female Yorkie spayed, if you will not be breeding her. Doing so will greatly cut down on her chances of developing ovarian and/or mammary cancer.
