Might as well add feral cats to the kill list, the damn things aren't even supposed to be here, and there's no telling the impact they have on quail populations.
Now the dog deal, I pretty much grew up in the country, and there's no telling how many dogs I have killed. Folks would bring them out from town and dump em, they get in trouble pretty quickly, killing chickens, chasing stock, whatever, they get killed. It was always my job from the time I was a kid.
It's not always strays, several years ago some folks near here had four nice labs that they let run. They thought they were just family dogs and good pets, but they killed a colt that was a few months old, and came after my young girls that were playing behind my folks place. I had been after those dogs for a few days because of the colt, and just happened to have a rifle close by. I got them all, we dug a hole behind the pond dam, and nobody knew where those dogs went.
I lived on a place one time that had a good chain link fence around it, at least I thought it was good. It kept a female doberman of mine home, but she came in heat, and one morning I went out to warm the truck for my trip to work and had a pack of male dogs of all sizes and shapes in MY fenced yard. I figured that I would just run those mutts off and put my dog in a shed, but a couple became aggressive toward me...in MY yard. I thought about my young girls, who played out there all the time...in my fenced yard, and went back in the house and grabbed my auto loader.
Boys there were dead dogs all over the place, some got out of the yard, but they didn't get far. We had some old coal pits on the place, and that's where those dead dogs went. Saved me alot of digging.
Now I strongly believe in having all my dogs neutered. It does improve their attitude alot.
I'm with the folks that believe in killin em, burying em, and keepin quiet about it.
