Sleep deprived, on edge, going nuts - yep thats generally how people feel after spending 15hrs with an adolescent. Sounds like he is relying on you a lot to entertain him.
How are you feeding him? All food should come through food puzzles and treat bottles/dispensers so it takes him a while to get through his food and keeps him occupied. It also teaches him to amuse himself.
Teaching him 'on your mat' and 'settle' is a great idea. Get him to practise his stays and throw some toys onto his mat so he learns about quiet time.
Normally he is great at entertaining him self. We use to call him the one man party.
He gets fed in his crate 2X/day. Now that I am training more I will have to reduce the food. He gets food in a kong when left in his crate when I go out.
My other dog Maverick does not chew when he eats and inhales his food. So I have a feeding crate for Ryder so they dont get stressed over taking each others food. I take turns on who gets his bowl first.
Thanks for the feed back. I appreciate it
