The puppy is very small and fragile but the sister would throw the puppy around, throw grass at the puppy, and hold her by her arms in the air. What makes this abuse even worse is that the puppy is too young to even cry or whine. I want to take matters into my own hands and call police or something but I don't think it is my business. Anyone out there, should I be involved for this injustice or leave it be?
