Antigone, I've heard many comments regarding rescues (or coordinators/fosters) who 'keep dogs for themselves' and would like to address that issue. I live across a provincial border from the 'puppy mill capitol of Canada,' and have become an unwilling expert in rehabbing & rehoming PM dogs. I don't think you--or anyone else--would make that comment if you'd actually cared for one of these dogs. Moreover, it's difficult to find appropriate forever homes for many of them, since they come with behavioural or health problems that adopters either aren't equipped or willing to deal with.
I've adopted two of my own fosters: one so incredibly timid that I've never been able to pick him up or put both arms around him unless he's tranquilized, otherwise he bites; Another I received as an 8 week old foster with cranio-facial trauma--he's visually impaired and is mostly incontinent, although he's improved somewhat over the years. I didn't 'want' to adopt either dog--I wanted to continue fostering--but the fact remains that they--and a number of PM dogs--were and are 'undesirable' to the average adopter, and often remain with the foster parent.
Also, even PM dogs less impacted by their experience awaken a protective instinct within their foster parents, who then--not surprisingly--become unwilling to give them up. I can vouch that it's very, very difficult to nurture a broken creature who comes to you encrusted with feces and mange, who stinks to high heaven despite repeated baths but still needs the warmth and security of curling against you at night--then 'betray' them by handing them over to a stranger.
The thing to keep in mind is that rescues are about keeping the dogs safe and happy, first and foremost. Often the best home for them is where they feel safe and loved, which is sometimes their foster home. Anyone who gets mad at THAT probably isn't the most ideal applicant. If someone really, really wants a rescue, maybe they should become a volunteer first, just to see what's really involved with caring for a rescue. Contrary to popular belief, young, unaffected rescue basenjis are few and far between.
