Do you have some kind of Bison hunting air rifle or a Girandoni? Even a top tier .177 rifle pushing ~1200fps isn't going to do much of anything besides getting lodge beneath the pelt.
You seriously need to do what >>37589475
says and just report the owners for animal abuse. It's not like calling the cops on crackhead neighbors, people are serious about coming to fuck someone up for abusing animals.
Or just be a real boss and contact shoot them in the noggin with a .22. Skulls make a good temporary suppressor. Source: personal experience executing piggly wiggly for pig pickin's over the years.
I've also had similar issues with ranging mutts terrorizing my neighborhood and eating all the cats and chickens. We're rural though, so I handled that with the .22 in picture related and left dog and a bag full of mauled chicken in the assholes driveway. That's what happens when people keep telling you to keep you dog under wraps or it's going to get fucked up.
