I have a pit bull/dalmatian mix (at least we think so) and she has “murder” as a significant part of her brain considering she’s happily killed countless animals (and brought many through the dog door). She usually doesn’t eat them, she just kills them and hangs on to them like a trophy until we can get them away from her, which is not easy.
Also, the best day of her life is when some stupid bunny decided to give birth to her babies in our back yard and she found them and ate all of them, slurping them up one by one like spaghetti as we watched in horror. It was the best day of her life.
