Hi there I am expecting my new yorkie puppy in March it is a little girl.

I am a Mother of 3 boys and a male Lhsa Apso. I am so excited

to have a female to join my family of males. The one thing I am concerned about is my Lhsa Apso he is 18lbs and is very gentle but I am concerned if they play he may hurt her. If anyone has any suggestions I would appreciate any help. Thanks
