I don't, for one minute, think that dogs, cats or other predators, have a concept that we humans call "murder". Killing of other animals, be they of the same species or a different species, is usually either a predatory behaviour, in which case we can hardly expect these normal, hard-wired instinctive behaviours to be completely masked by domestication, training & a full tummy. It's up to us to manage these situations. Or based on fear, possibly fear of the unknown, fear of very strange behaviour in another same-species animal, fear of being attacked by a fitting animal, fear of the noises made by an animal in pain etc etc.
Very rarely in domestic dogs, fights to the death, or at least inflicting severe injury, are caused by competition over resources, e.g. the right to mate, the protection of young, protection of territory. Dogs are social creatures & have developed communication systems to give warning signs to prevent such conflicts. Even a couple of dogs scrapping over a bone are unlikely to fight to the death & any severe injuries would possibly be caused by an unlucky bite to the jugular or something, rather than a pre-meditated & deliberate act to kill.
Dogs are biologically pre-disposed to be social creatures & to communicate with each other via body language, vocalisation, sight & scent. Their communication systems are relatively sophisticated compared to lots of other more solitary species ~ so maybe, when for reasons unknown to us, & completely out of context & perhaps frighteningly for the dogs, these communication systems go wrong, just maybe, it is a HUGE thing for some dogs. It could be so scary that they feel the need to attack & maybe this is heightened even more by the fact that this behaviour is coming from a dog that they thought they knew very well, & found very predictable. I don't always like human analogies because of the risk of anthropomorphism, but imagine how you'd feel if your mother/father/son/best friend etc suddenly turned on you waving a gun/axe (substitute mouthful of sharp teeth for a dog)
. This would almost be worse that getting attacked by a psychopathic stranger or a drugged up junkie, or surprising a burglar!
And then if you consider some other species in the feline world, infanticide is rife
. Male lions & male cats will kill young offspring that they haven't sired, solely to bring the female into oestrus so they can mate & pass on their own genes. This would be absolutely abhorrent in the human world, but is an evolutionary successful & completely normal behaviour in the feline world.
IMO if we allow our pets to be together unsupervised, then we take those risks ~ but personally I'd rather allow my dogs the comfort of company of their own species, than separate them when I'm not around. And my cats also mix freely with the dogs when I'm not around. It's a risk I'm prepared to take for their well-being & happiness.
