@cmd:
PS: I checked out your homepage and noticed you have Select Basenjis. Our Bonnie is Select Bonnie Bell who's parents are "Gator" (Emerant's the Instigator) and her mother is Dr. Tracy's "Peeka" (Select in my Pocket). Ramse is a Klassic Basenji and our Brie was J'Tai's Breeze of Trouble from the Hacker's line… I guess I better post an introduction.
Yep, we have three Select Basenjis And we know tons of Klassic Basenjis…both wonderful breeders. I saw Peeka when she was an itty bitty baby
I wish I had some good advice for you. In my experience, it works with the girls until the day it doesn't. And once girls have a fight, they never forget...where as the boys seem to get over it more easily. I think, if I were you, I would definitely go with a boy....and I would probaby go with a baby so there is the best chance of all dogs bonding early.
Good luck, and let us know what you decide, and how it goes.
