The only reason I don't keep them all (well we've kept 2.7%!) is because we foster through a rescue group. We get to pick them out (Except for the returned dogs) and get any behavior or health stuff worked out and give them the best chance at a happy life as we can!
Aside from the emotional support from the fellow rescue group people (especially at the beginning, I spent my share of time at the back of the pet store crying when my favorite foster was adopted, and the rescue ladies were reassuring me that that i was doing the right thing!) we couldn't really foster any if it was on our own money. The food alone would be expensive, can't IMAGINE the vet bills, the adoption fee rarely covers all expenses (it may be close for a healthy adult, but puppies need more shots, and any extras like a skin infection would cost $$), but our rescue pays for or supplies us with everything dog related, leashes crates bowls shampoo towels brushes collars hw meds....
Perhaps there's a rescue in your area whose philosophy you agree with, who could let you foster with them?
(A decidedly unhorsey) MrB knocks over a feed bucket at the tack shop and mutters, "Oh crap. I failed the stadium jumping phase."
(he does listen!)
Through no fault of anyones, he is now in the rescue pipeline and quarantined for at a minimum of ten days, etc. etc. etc. And will be difficult to get ahold of.
Funny, they said they need to quarantine him to be sure he doesnt have anything contagious... When I questioned a very young dog being isolated they then said he would be socialized with people and the dogs at the vet hospital.

Dogs like him are why so many rescue groups in the northeast are heading south and bringing adoptable dogs home. Here in NJ, almost all the shelter dogs are pits or pit mixes. Don't want to get into that argument but suffice it to say that a lot of people don't want that kind of dog. I guess spay/neuter has been pretty successful here but not so much south of the Mason/Dixon Line.
