Have you ever/would you ever?
I know some people would never rescue a stray due to concerns for aggressiveness, diseases, hated of animals, etc.
I've rescued two stray dogs before.
One was a Jack Russell, running down a straight in the country. I stopped the car, pulled over, and the dog got into my car. I went knocking door to door until I found its owner, because the dog wasn't wearing a tag.
The other dog was a pit bull that was running up and down a busy street. I, again, stopped the car, pulled over, and the dog got into my car. This dog was wearing an ID tag. I called the owner and got the address for the dog, and returned the dog safely.
