I need some advise. People around here let their dogs roam free. They chase my colony cats and eat their food. Most recently, some people here got a puppy. Sometimes she wears a halter. I was thinking I should buy a leash and tie her up while my cats are eating. It's not cool to restrain someone else's dog, but I don't know what else to do. Is there any training things I can do, in that short time that I am feeding the cats? I have never had a dog, so I don't know how to make them obey. Contacting the owners doesn't work here due to language and cultural barriers. People think it's fun to have them chase cats.
