I have coyotes in my backyard, side yard, front yard....Okay, I live in the middle of the woods. However, food for the coyotes is plentyful, so they pretty much stay clear from us here. But I can pretty much bet that your pack is not getting enough food. You should call animal control and see what they say. They should have to do something. If they are coming close to your house, they are posing a threat, not only to your pet, but to you. If animal control doesn't want to help, I would recomed getting press involved. Do you know how bad animal control would look if they refused to help people with a problem like this? Are there small children close to where the pack is living? When you talk to some one, bring this up. Don't center on the danger to pets, center on the danger to humans. They are more likely to help then. Unlike us here at Pets, some people don't care about pet saftey, but they would about people. And by all means, keep us all posted, and good luck.
