Hi, i’ve had a similar experience with a litter of 5 puppies. One of them is a very small female puppy, it is obvious that she is growing unnaturally slow compared to the other as she can barely walk even if she’s passed a month old. It has been normal for the past week with the other puppies picking on her sometimes but not rough at all. Then recently her female sibling suddenly attacked her with no intention of playing. The female puppy picked her up and swung her around, the little one kept squirming and crying because she couldn’t do anything with her weak body, i was trying to separate them but the bigger one was very aggressive and bit even harder. Luckily i got to remove the bigger one but unfortunately, the little puppy had a very big wound on the side of her belly that we cleaned and covered. I am really confused why her sister would do that without any provocation coming from the little one. Can anyone please explain why?
