I think stray dogs are a much bigger problem than people realize. I live in a beach area and I see visitors visibly scared or upset by dogs that are threatening or at a minimum begging. It's not a good experience in either case. There's a kind soul in our area who, with a local vet, has captured and spayed or neutered 75 stray dogs so far this year. An amazing number for my little corner of town. Who can say how many of those visitors never came back costing the local economy revenue.
