I hear you. Took Mulligan ( who it turns out is a girl) to the vet on Thursday for her first shots and deworming, and his assistant said that over 6000 cats are euthanized every year in our area. In fact the situation is so bad, that they are now spaying/neutering as young as 8 weeks old and no pet is released to a home before it has been fixed. Clearly there are a whole lot of irresponsible pet owners out there. 
My appointment was actually delayed because a farmer had showed up about 10 minutes ahead of me with 2 out of 3 feral kittens he had been able to catch. The mother cat showed up sometime in the winter (likely discarded by its owner ) and somehow they managed to survive, momma cat has disappeared. He was getting them wormed and rabies shots and, I hope, fixed. Even so, their prospects are not that great being something around 6 months old ...
I think rescue workers are truly angels - because at times it must be just heartbreaking!

I can't shake the feeling that if this family didn't care about the dog, they wouldn't have offered it to the rescue where it came from.
