Good advice above. Do keep in mind that your puppy is trying so hard to figure out this human world, and what the rules are, and what's ok, and what's not. He doesn't have his mom and brothers and sisters to teach him "in dog speak" anymore, but is now trying to figure out human communication and body language. If your boys are teasing him, and at the same time you're trying to teach him not to jump up or play bite, he's going to get very confused. It still may be cute now, but I guarantee you that in another 2 months when he's bigger, stronger, and his teeth are a combo of adult and puppy teeth, it will no longer be cute. Great advice above to have the kids help you, really praise them when you catch them doing something right - just as hopefully you're doing with the puppy!

(That works wonders, by the way - for both species

- huge praise rewards for the kids <and maybe extra video time or ?> and a big "good boy!!" and a treat reward for the puppy). Explain why throwing the dog's toys out of reach isn't nice (they're old enough to understand) and ask to not to that anymore, and instead encourge nice play, helping with simple training (as Running dog suggesting above), and maybe find some fun training games (such as round robin recall, standing in a circle maybe in the living room and saying his name and calling the dog to each one of you, "Harley, come!" giving a treat, then the next one calls the dog, gives a treat, then the next one...). Games like that get the kids involved in training, the dogs learns a good recall to everyone in the family, and it's a win/win for everyone.
