Buzz turned 10 months old on Saturday. He seems to be full grown (around 55 pounds) and he's really started to have a more mature personality. He's still super-friendly and nice to people, but has started to accept that he doesn't get to greet and cuddle every person. He seems to have fully accepted my leadership and no longer jumps on me or second-guesses me on important commands like "quiet." His recall is not 100% and he is slow to complete some commands, but it is all very workable. Buzz's house manners are almost 100% in place! He's been housebroken for several months, but he seems to have really internalized rules about what he is and isn't allowed to chew on, dig at, pull over, and sit on.
This month, Buzz started to show his disapproval for puppies. He was mean to several puppies at the park. So, for now, Buzz is not allowed to play at the park. I'm hoping that puppy-hating is a stage he'll get over and we'll be able to go to the park again in a few months. In the meantime, I'm going to put up a 25-foot stretch of fence in the yard so that the yard will be completely fenced and Buzz can have off-leash time at home and we can do some fun training in the yard.
On a funnier note: Buzz has learned that getting in the bath is a way to earn treats and has started to spontaneously offer this behavior.
