Hard to say whether the breeder will take her back. I'll ask.
The owner isn't willing to "give" Tiara to anyone, she wants the adoption fee.
Tiara belongs in a home without other dogs or children, lots of one-on-one training, long walks for exercise, high quality/low-fat/low-carb food, and a stress free environment.
It is disturbing that a six-year-old Basenji is looking at yet another home. I should stop looking at petfinder.
