We adopted our dog, Brody, when he was 7 months old. He did a lot of jumping up and putting his mouth on my arms. He would also get a little crazy in the evenings, running around in the house very quickly and making growly sounds. It was a little scary to watch, but he wasn't being aggressive. He was just burning off extra energy. Sometimes people call this "the zoomies", which I think is very accurate. Since I started taking Brody out for regular sessions of fetch, even 20-30 minutes where he can run at top speed and get good and tired, he hasn't done this very much at all.
To stop your pups from jumping all over you, try to ignore them. When they jump on you, stand up and fold your arms across your chest and turn your back on them. Sometimes you might have to walk to face into a corner so they won't jump on your front. Even if they jump on your back, don't look at them or speak to them. This is very important. Wait until they are quiet and all four feet are on the ground, even if it is just for a few seconds, then turn and praise them. They will learn that they won't get your attention by jumping up on you, but only by sitting or standing quietly. It takes a little while, but it does work. When I did this with Brody, he would jump up on my back and nip at my arms or bite my hair and pull on it, but I just waited until he sat down before I turned around or spoke to him. It took a couple of weeks of doing this every time. It even seemed to get worse before he eventually stopped for good. This is common and is known as an extinction burst, where the dog knows he is going to quit doing something, so he does it as much as he can before he gives it up forever.
The videos that Danielle posted are excellent. The trainer is Emily Larlham, and her YouTube account is called kikopup. There are many great videos that show how to train your dogs to do all kinds of good things, as well as helping them learn not to do the bad things. The methods she uses are very gentle and quite easy to learn.
