I think a big part of this is regional though- any and all loose dogs here are someone's pet.
And this is why we should not be judging those who do SSS. Around here, most stray dogs are not someone's pet. I live in a rural area - where we have real farms. Most neighbors are a mile apart or so. We all know which dogs belong on which farm. (Because we see them in the yards as we drive by - most of them stay on their own property) The loose or stray dogs around here are usually dumped off by irresponsible people. They get left during hunting season because they're gun-shy, or they get lost (you know about those, though, because the the owners call the radio station and put ads in the papers). Other people think it's just fine to dump dogs off in farm country because farmers always want another dog around, right? Around here people are responsible pet owners which also means not having more animals around than you can feed or care for. We'd rather have our one or two dogs that can run round loose on our hundreds of acres of farmland than have several dogs that we have to have penned, caged, or tied up. So, agreeing with cafarmgirl, I think SSS should be a case by case basis. I won't judge you for taking in all the strays you find, but I would also ask that you show me the same respect for doing what occasionally needs to be done around here to either put a poor abandoned animal out of its misery, or for protecting my family and my flock. The only "animal control" around here is what we do ourselves. Sure, there's a shelter here. It's our local vet who will take them in and try to find homes for them, but fincances being what they are around here, it's hard for them to do so. They rely on donations, and those aren't coming in fast and furious.
Answering OP's original question - I call myself "Pro-Gun", I guess. I grew up in a hunting family, and married into one. We hunt duck, pheasant and deer. We also shoot predators that wander near our buildings. There is plenty of space for them in the fields, near the ponds, and even in our huge grove - they don't need to come near the buildings. Skunks are shot on sight because they are major carriers of rabies. Possums have to go because I have horses and don't want to chance EPM. Coons because they're destructive. They can wipe out a patch of sweet corn in a night. They take a bite out of each ear, knock the stalks down and move on.
OP - thank you for opening up an interesting topic. And thanks to those who can answer nonjudgementally. It's been fun reading most of the responses.
