"A Basenji is a slob's best friend"
Remember that and you will be right. It teaches you to pick up and put-away things you don't want destroyed, chewed, or nibbled. Especially the crotch out of underpants, the right thong/flip flops (so that you finish up with left ones untouched), your Mother's best coffee table, your best plant, (they will always pick the "best" that you have if you have multiples). I feed mine RBBB cut into chunks by the butcher - but wait until the pup gets their adult teeth. Good luck with your pup.
and while he is so young, can you visit him? get to know him and let him get used to your smell. make sure he gets the puppy shots, and the forever shots (like parvo). Try not to take him home until he has about 10 to 12 weeks of age, (as late as possible, is good). Check out Mum and Dad on the zande database, OFA, and find out as much as you can about the breed traits and habits. buy a crate that he will grow into, the crate should be big enough to stand and turnaround without touching the side, or top. That will be useful to bring him home, and take some bedding so that he will be used to the new smells. Good luck.
Go to the Zande website, and included there are some material about getting a Basenji, or not. It does not sound like your environment is right for a Basenji. The temperature upto 34C is okay, but after that they start looking for shade and the cooler spots. When it is hot here, above 40C, the older girl I have will walk, but when there is some shade she will lay down until she is ready before moving on. They are in control, and let you pamper to their needs, but they are definitely trainable.
For their adult teeth, Raw Beef Brisket Bones (RBBB). These bones go into nothing, so they will not crack or chip the teeth. Keeps their teeth white and good smelling breath. Whatever you feed them use the hammer test - if the bones splinter, then they are not for dogs. No cooked bones, ever.
we still have "butchers" here in Australia. these are usually local shops, that sell meat. After they have cut up the large sides of beef, they are left with some bones. The bones you are after are the breast bone, which is usually discarded as waste, but is good for dogs. Get them to cut the bone (which is about 1 metre (about 1 yard) long), into the size that is good (mine are cut into chunks about 7.5cm (about 3 inches)) or whatever size you want. The cutting is done on a bandsaw so no effort on their behalf. The advantage is that there is no debris left for the motor mower to fling at your windows, or for insects to settle on. Even at the supermarkets there are some to be had, but find out from the meat section when they get deliveries. You will pay more at the supermarkets, but you should not pay more than necessary.
I even had a bitch that hung on for 24 hours because it was raining. Eventually I coaxed her out and she kept very close to the walls and under the eaves to toilet. I put a collar on and lead, and walked her until she went in the rain, but as soon as she went, she insisted on going home, about a mile away, and she spent the rest of the morning getting that nasty water stuff of her.
Another time, it was really hot, and she was happy to paddle in the shallows of a major river. So they will get wet if there is a good reason.
They can all swim, but all choose to avoid water at all costs. Whether it is rain, dew, or puddles, they will try their hardest to avoid it. As for bathing, I use the criteria that they will need it when they get one. I found when showing that a bath 2 days before a show will bring the gloss back to their coat.
