I am adopting for the first time. I was wondering if anyone had an opinion - there is a 12 year old male yorkie that is available super cute and energetic - and an 11 year old female maltipoo. Has anyone here adopted a senior of either breed or owned one of these breeds? Do you think one will live much longer than the other? They are both super sweet - I haven't met them in person. One is closer to home and the other is about 4hrs away. Any ideas or suggestions? Experiences with senior doggies?
