I have a Labrador mix and I'm unsure what type of line she is. She is friendly and gets along with other dogs pretty well. She loves people. She has a lot of energy but she is calm most of the time. When trying to train her, she tends to understand it then forget it or not listen even if that's all we have been doing. She likes to play tug and she likes to go fetch the ball but not bring it back. I'm not sure what else will help to see what type of line she is. We think she is mixed with Cane Corso.
