put the dogs inside.. try actually calling like she said.. when he comes.. feed him..get him comfortable..cage him.. call the pound. I love my bullies, and hate breed specific legislature but I also hate people who have vicious dogs and deal with with in the wrong ways.
Thats a bit rash I think.. why would you call the pound over a neighbors dog.
That could technically be something similar to stealing the animal, the proper thing to do is to call animal control, and they will talk to the owners about the animal.
