When I went to visit my neighbor one day, I discovered a scene that broke my heart: a mother dog biting her own puppies. He cried in agony as he rolled about on the ground, the little puppy. I promptly grabbed it and proceeded to examine it for any bites. Initially, I was under the impression that the mother dog was attempting to discipline her young puppy. However, the neighbor disclosed a disheartening truth: this was the sixth puppy that she had; the previous five had been killed by being bitten. It was only this one that had made it.
