Ditto, ditto, ditto to everyone's remarks.

Patience and constant suprivision are a must! Invest in some puppy prep materials.

If you can't watch the dog, even while you're in the shower, it needs to be contained in a safe-zone. We have a pet playpen 4X4 with a cage top where the dog's sleeping and eating areas are contained. The dog sleeps there when we're in bed and cannot destroy the house at night or while we're away. We also tacked some rabbit wire fencing around our existing rickety wooden fence to prevent escapes.

Other than that, be consistant with training and always give treats if you expect them to listen at all. Positive training works best. My girl flattens her ears and persists in her task if I try to herd her out of the way by force. But produce a treat and happy-happy yes ma'am! Can we do that again?

Knowing the possible problems with this breed helps you to train sooner so the dog doesn't develop those bad habits to begin with.

Last March I also decided to take the plunge and own my first Basenji. It had been decade since I owned any breed of dog and I hadn't even heard about Basenjis until I did my research and chose a dog that sounded compatible for me and my husband. My husband was not interested in any dogs so I had to really do my research. I almost got cold feet too when reading about the counter surfing and stubborn behavior. But after doing my homework like you are doing now, my husband and I agree that this is the best dog ever!
Hope all works out well for you, mine worked out better than I could have imagined!

I'll tell you what my vet told me at least twice: back off on the feeding a bit. I porbably feed my 6-1/2 month girl 1-1/2 cups daily or 1 cup if she's getting alot of training treats. The vet's opinion was that you should see a waist when looking down at them standing. You should also see a slight hint of the last two ribs. I can't quite go with the ribs suggestion, but my puppy is a little less plump around the belly. Other than that your puppy is adorable and with the ears I personally feel the bigger for a Basenji, the better. But your puppy's ears look like she'll grow into them. I like the white making the neck look more elegent. Mine has alot of while too and she disappears in the backyard hedges, true camoflague! That's about the only time she stands still.
