There are some breeders out your end of the Country that could probably help you out. Cheryl Myers Eggerton is a Judge and also a breeder, she is in Minto NB and has Connamore B's, Simone Guadet (Beaubri) is on PEI, Valerie Rodger (Miloki) is in Beaver Bank NS.
I have two that I can leave out without issues, and two go in the crate when I am not home. It is all dependant on the dog. But, like Anne states, puppies are a lot of work and sometimes the older dogs, young adults and retired show dogs are the better ones to start with.
You can find all of the above on the Basenji Club of Canada website under breeders. At least with Val, you could probably visit her since she is in NS directly.
Let us know how it goes,
