Hi,
I just got a second female Yorkie.

I have one already and she is 2 years old, her name is Maya. Maya is not aggressive or something but doesnt seem to care for her. This is only Bella's first day here so I am not too concerned but just wanted to get some information on how to handle this from day one so the two will get along in the future. (aside from giving Maya the same attention as before)
Thanks!
P.S - Bella is 10 weeks old.
