i say "go for it!"
sounds like a very nice puppy
of course he will miss his old family but which yorkie baby didn't miss their mommy and sibilings when we first brought them home?
milu was so cute when we brought her home. you could tell that she misses her mommy and siblings. but also she liked us because we are very nice to her and splurged her with attention and love! and treats! lol it took her about 3 days i think to forget about her old family. lol
hope you get the puppy, and don't forget to show us pix!
