We would definately get a puppy. From what I've read that does make a big difference. I've also read to ask the breeder if the puppy is submissive. I didn't know that they could tell that at such a young age. Allie was never dominate towards my mom's dogs when we would visit. It was only when we brought Maci home that she started that. Even when she was a puppy though she would get in between my husband and I if we were sitting next to each other on the couch or if he would give me a hug. I will post some pictures soon, I have to figure out how to do it.
Thanks for all the advice so far. I really appreciate it.
