Hey you guys, the OP here! I just wanted to clear some things up. My puppy is very sweet. She has never pulled anyone else while on the leash. She's actually one of the most timid dogs I've ever owned and yes, I have owned dogs before and I know the breed. But because she is a puppy anomaly and doesn't pull, I thought it would be ok for my niece to walk her as I walked next to them. Also, this took place in my fenced off back yard. I do however have a stone terrace, which is where my niece got pulled over on. I know that my niece getting hurt is probably my fault and I've now learned that my puppy goes crazy when there are squirrels in sight. I've apologized to my sister-in-law. My niece is fine, she was back up and playing within minutes, but her mother wont let her near my puppy and I got a talking to. So, hope that clears some things up for you guys.
