@Cassie This is sad- sorry that you had to went through this, this is more than just sad- this story reminds me a bit of Puma, a cute cat.
Ik a pitbull is a dog but what the pitbull did is just terrible- How can a fucking pitbull this fucking aggressive, i think the pitbull has to get more discipline from the Parents- Its a sign that the parents didnt give them enough commands (I didnt know how to call it else so thats why i just said commands)
