Got to love the teenage stage 
Basically as I say many many times control and management is the best way to go. Try not to let them practice the behaviour that is nnot appropriate. Up the focus games on you. This will depend on the dog you also want to keep arousal lowish and not too high for too long.
So tuggy games may be great for some dogs but too much for others.
I can not push enought the benefits of sniffing and seeking games.
You may need to up the reinforcements/treats during this time but this is fine this time will pass (honest!)
If your dog is chasing and playing with dogs and losing all recall prevent this from happening but limiting the opportunities for this to happen. Walk in quieter areas, have meet and greet walks on the lead only.
Perimeter chasing is very rewarding for the dog the longer it goes on for the harder it will be to stop it. I would prevent him from going out in the garden on his own. All activities in the garden needs to based around you, so games and scatter feeding is your secret weapon here. Scatter food in the middle of the garden and let him search.
Increase his training on sit with a release command. Do this away from the door and over praise and reward when he will sit for a few seconds. Then add this to being by an inside door etc, then eventually add to the outside door.
In teenage years it is good to have a settle on a mat as this gives the dog and you a chance just to chill.
heatseeker what breed is you dog?
