Crabo;
I was but a lad at the time, and that time's been more than a handful of decades ago, but I did see the solution to your problem. And it's not a firearm.
Greyhounds that aren't fast enough to win at the track are frequently and constantly culled from breeder's inventories. Mostly, they're killed. But you can "adopt" them if you care to. They won't be family pets though & that's where most people who adopt them get into trouble. However, when I was working a summer job on a ranch in Wyoming, the rancher knew, or heard tell of, another rancher who had some adopted greyhounds. That rancher used 'em for coyote dogs. My guy took me along to see what it was all about one fine summer day.
The dog owner had put out a carcass the day before. He'd laid it where he wanted it, which allowed him to get his dogs into position without disturbing the coyotes. Greyhounds are fast, but don't have a lot of endurance. But, he sicced the dogs on a coyote that was feeding & the show was on!
Dog A went straight at the coyote, dog B headed out to the right a bit, & both closed on the coyote rapidly. Dog A hung just off the coyote's left flank & dog B curved in. The coyote was looking over his left shoulder at A. B hit the coyote on the right side like a bomb & then they both tore into it. I almost, but not quite, felt sorry for the coyote. Seen too much coyote damage to care about 'em.
Now how that guy trained 'em to operate that way I have no clue. But man, it was spectacular!
