If there were loose dogs the answer is that the SPCA or animal control service will pick them up and try to find good homes for them.
I have my doubts. I tried to turn over a stray to the SPCA and was refused, and to give it to the pound, where it would be killed.
No,not in larger cites. The SPCA will not pick up dogs and charges a hefty fee if you bring a dog in. As to the Animal Control, they don’t. You are on your own.
