You will also want to think about evaluations, treatment, training, medical, advertising, and more. All of these will be addressed in my "how to start a rescue" section.
Now, in the case of a shelter scheduling a dog for destruction merely because the time has expired, we will intervene. In such situations, we evaluate the animal's temperament, and discuss the physical shape with the shelter vets. Assuming it is salvageable, we would pull it from the shelter and accept it as a rescue.
Animals found running loose are another matter. Without tags, it is pretty hard to determine where it belongs. We accept stray dogs of the Samoyed breed found running the streets. But we also check out calls regarding strays, to make sure it is for real. Sometimes people report the animal as "found", when it was really the family pet. Deception does happen, and we try to make sure we are really dealing with what we've been told.
The last reason we will accept a Samoyed is if another rescue program outside the Breed accepts it and needs our assistance. It's professional courtesey.
Severely ill animals drain away the rescue budget quickly. While we would treat a heartworm-positive dog, we wouldn't probably treat one with brain cancer. For every dog, we must decide the case.
Now, when you accept a dog because the owner simply does not care, you are cleaning up after the irresponsible human. If the owner really cared, ads would have been placed in the paper. Efforts would have been taken to find a suitable home. Otherwise, you are sweeping up the mess.
