Lucky me, my first pup was a GR/Yellow Lab mix-the best of 2 wonderful breeds. I got him as a wee pup and it did take 5 years for him to settle, but we never ever had a problem with him. Just gave him lots of excercise and training. He was easy to train and as smart as a whip. He had his "moments" (loved trash cans, anything paper) but as long as he had 2 tennis balls in his mouth at all times, he was content. I had had no dog experience, so I didn't, unfortunately know to socialize him well, or know about "alpha", but that was totally my fault. I'm glad to hear you did some research and decided the best breed for you. All dogs are different. My friend's yellow lab was also docile and laid back. Cody's mom was the GR, and as calm as could be, so chances are, his dad was the active one. The dog you're chosing is totally gorgeous!
