An elderly, frail visiting dog is killed by an eight-year-old male Cane Corso X, and the dog’s owner’s roommate is asking for direction.
The movie the Lady and The Tramp wasn’t a canine behavior documentary. Not all dogs, due to the nature, and, or nurture reasons outlined above are inclined to live with other dogs. However, sometimes we set them up to fail. There are options, and results vary. With enough effort, it’s technically possible to force dogs that live together to behave, but that’s not the same thing as enjoying living with other dogs and can be very stressful on one dog, or the other(s), and the owner.
Unfortunately, because the world of dog training is driven by people (trainers) that love dogs most dogs end up being influenced more by their hormones, breed genetics, bloodlines, and evolutionary programs alone, as opposed to these things AND a loving authority figure in the context as is universally found in higher order social species such as dogs, wolves, apes, humans, etc. Here’s how dogs are often led astray, and needlessly become aggressive with unfamiliar dogs. – John Wade
