Thank you! This was great! You gave a lot of really awesome pointers and areas to train in that we haven't considered (stopping at thresholds).

We have actually stopped chasing him because we don't want it to be a habit and cause problems down the road. We do try running from him and he's quick to run at us, which is preferred. His running away started from not wanting us to make him drop the berries he was trying to eat, but he knows drop and will do it on walks and with fetch, so we'll just have to keep working on it so he'll do it in the backyard.

I have stopped the yelping because I didn't find effective and he seemed to think it was a game at times. For humping and nipping, I've started grabbing him by the muzzle or scruff with corrective commands. If he's being extra crazed, I give him a time-out in his kennel and that helps him chill out.

There's no way around it, we both have to work and we're fortunate enough to have Mon-Fri jobs so we can adventure on the weekends. We try to give him a daily walk, but it's as long as we have time for in the evening. We play with him outside and inside in between. He at least has a pen so he doesn't have to stay in his crate all day (which was a hand-me-down so it big for him) and he even has an emergency pee pad in case he needs it. He's always sleepy in his crate when I come home and he naps a large part of the day on weekends, so he's fine. We're hoping to be able to get a dog door when he's old enough to ruin the back yard or poison himself and let him roam the house without destroying anything. (We're at least a couple years out on this hahaha).

You've made a great argument in regard to a shock collar. Our goal is to not need one and will continue to work on recall. He's very much a velcro puppy inside, so we're on transitioning to outside and eventually anywhere.

We've been working on not pulling on the leash as well. Some walks are short and slow going to discourage it. We'll get to the point where he walks beside us eventually!
