Boy, he's one you just want to hug the stuffin's out of, 'cause he's just too adorable! Have you growled at him when he's too "rambunctious"? A very growly "noooooooo," will often help stop some of that stuff, but, like Ginger, you want to ignore him when he's out of line. As many have already advised you.

Taking your cues from Ginger is a good way to deal with Bob in "his language," and I, too, advocate lots of socialization in classes and at the office, especially if there's lots of folks he gets to meet there.

When I used to teach puppy classes, I would do some odd things. lol Like bouncing a basketball around the puppies and then let them check it out. Had a 6' long kids tunnel that we'd work with them on, from each end, since the view is "different" from either end. These are things you can do with Lizzie's help (in fact, everyone in the family can participate) and will teach Bob (and Ginger if she wants to 'play') trust and where he belongs in the family.

Teaching tricks, such as shake and high five can also help establish Bob's place, since everyone in the two-legged aspect of the pack can work with him on learning these things. Sets some of the "rules" of the pack--I give you a command, you obey, you get a treat and praise. Even simple things like sit and down can be taught at this age and help him understand that he is not the top dog.

BUT, we have to remember that he's still a baby and will "forget" from time to time. So long as you are consistent, he'll learn it all and be a great dog. Sounds like y'all are doing a great job with him so far!
