Cheaper Than Dirt sells less than lethal rounds for shotguns. Bean bags and whatnot.
Just remember that dogs' bones ain't as strong as people bones and those bean bag rounds are made for shooting people.
OOH! Bear spray! Hot fence! Look into non lethal stuff and be smarter than your varmints.
All that said, if it's a pregnant mom nesting you're gonna feel like a heel if you hurt her. If you wouldn't feel like a heel for hurting a pregnant dog, I don't like you.
