This is my second time asking this question and i got some good answers last time and im just wondering the good and bad stuff about these dogs? My mom said there mean because my uncle had like 2 an he taught them sit or stay but he never really did anything if the would bite. He just said NO and then that was it. So im trying to convince my mom to get me one andi need to convince my grandma to so can you PLEASE tell me a little more about them. I'll give 10 points to the person with the most details and says all the ups and downs about these dogs. Thank you SO much for helping me i really really appreciate it.
