I have recently got a 12 week old lab puppy. She is awsome! My daughter has a 7 months old chi who is very acitve. (male) the two of them play and bite all the time. At night however, I noticed the lab gets very aggressive and growls and bites more than usual. On her own, she is passive and quiet. She sleeps a lot during the day. At night it's like she is beside herself and chews and bites like crazy. I am having a hard time house training her. She is smart but not consistent with toileting. Does she need more stimulation, less? I just started training with her and I just started crating her. I had a lab for 13 years but got her at 4+mos and recently had to have her put down. She was the perfect dog/friend! I am having trouble connecting with this one in terms of training etc. HELP
