Boxer Insane
So I have to save up in order to take him, otherwise I would be taking him right now... I do try to socialize him as much as I can.
See if the Petsmart offers a free puppy play seminar--or any free seminars for that matter. Most Petco's around me offer a free puppy play session as well.
I do try to socialize him as much as I can.. most of my neighbors have dogs and he is learning how to be around them with out freaking out, it's just taking time. He's getting better at not launching forward when another dog barks at him.
Oh good. Group walks with neighborhood dogs and play sessions with appropriately behaved, even-tempered friends' dogs are great ways to socialize your pup to other dogs.
with humans I make him sit before anyone can pet or touch him and I give people snacks to give him so that he starts to see meeting new people as a good thing.
That is great, if he truely wants to greet the people. But if he is at all nervous around the people, making him sit might be causing him stress, increasing the fear, and making the experience unpleasant in his eyes. Watch his reaction and don't make him greet anyone he doesn't want to. Instead, give food just for him looking at that person or sniffing in the direction of that person.
I hate to sound like an idiot, but I don't know many games dogs play other than tug of war and fetch... also I do tell him to drop it when we play, any time he starts to try and take things from my hands during play I make him sit and fetch, but first I make him drop what ever it is he's holding... he doesn't usually listen unless I repeat it a few times but he does listen.
What kind of Calm activities can you suggest trying?
You can play tug of war and/or fetch, just play them with some rules and play them really low key. It sounds like you have some good rules in place--he has to sit before you throw the ball, etc. Just keep things calm--a few tugs on the toy and then ask for the "drop it" rather than tugging until he is a growly little devil on the end of the toy and then expecting him to be able to control his mouth or have impulse control. Keep the tug sessions short because it will get harder for him to maintain impulse control if the game goes on too long.
You can teach a nose target to your hand. This can be a fun game to play and is a great way to teach pups how to interact with an outstretched hand and can help with greeting people appropriately as well. Just hold out your hand and when your pup touches his nose to it to investigate, tell him "yes" and reward from the other hand.
You can teach him to "find it" by showing him a toy or food then hiding it behind the couch and telling him to "find it". Once he's done that a couple of times, you can show him the toy and run in the other room to hide it on him. You can play the same game outside and he can find objects or find people.
his arousal tends to be from either being hyped up, or just random... I don't think he's stressed out, I don't see any signs of it.
Stress doesn't always mean "stressed out" in the way we humans tend to think of it. Stress can come from frustration, confusion, social conflict, etc and range from mild to severe. Every dog exhibits stress a little differently, but there are some pretty common behavioral signals that dogs exhibit when stressed. It sounds like the humping your pup does is more from general arousal which is really common. I just didn't want to describe humping as a fixed action pattern without including that FAP's can be triggered by stress as well as arousal.
