So I don't own a dog, and not really thinking of getting one. But I do for some reason occasionally enjoy reading various dog forums. And lately I've noticed a few posts by people talking about their dogs all of a sudden snapping and killing their cats. Usually it was a younger dog, and a cat that would be considered senior age. Also it seems that they got along for the most part. What's disturbing to me is that in addition to the act even in places that specialize in dog training people make it seem like it's fairly normal and not really anything too alarming to the point that people don't think it's even worth it to take the dog to the vet. I understand dogs like cats are prey-driven and I suppose one could argue this is no different from a cat eating bunnies or mice caught in the wild. But I really haven't heard of people mentioning their pet mice or rabbit being eaten by their pet cat. On the other end I've seen people say that a dog killing a cat is a sign of worse things to come, but no idea if studies show that's remotely accurate. Thoughts?
