Oh, definitely, BRAT is still very active. Currently, there is only one Basenji listed on their website, but I know that there are many in various stages of rehabilitation who aren't ready for adoption. There is one currently in foster in OR, and they're trying to get some information about a pair that are in an OR shelter at the moment. Not sure what's in CA at the moment, but rest assured, there's no shortage of rescues out there. Do you have a current application in with BRAT?
I had a male Basenji that peed like a horse until the day he died at 15 and a half. No matter where he was. And it was kinda nice having a male that wouldn't hike his leg to piss all over things, never marked anything either. Don't complain if your boy doesn't hike to pee.
On the other hand, I had 2 Siberian Husky bitches who were TERRIBLE markers, always tried to get it as high as they could. They were both spayed too. One passed away a few years ago, still have the other, and she never marks anymore.
There is another Basenji on CL who is also from a GA breeder: https://louisville.craigslist.org/pet/d/purebred-basenji-pup/6625622891.html The owner is asking $400, sez he paid $800. BRAT knows about both dogs, but they won't pay a large fee.
Craigslist is NOT the place to buy a puppy. There is a probable scam happening on Craigslist right now regarding the sale of Basenji puppies. It is going on across the country, some ads have been removed, but new ones go up; currently there are ads in CA, CO, NM, OH, and FL. All ads have various titles, pictures, and reply-to email address, yet every reply I've gotten back is from: Suzan Lake <email@example.com and she sends the same group of 15 pictures.
She is giving away the pups, but she wants you to send $$ for airflight for them from Philadelphia. I smell scam, and there can't possibly be that number of litters available right now!
