He's throwing temper tantrums!!!

He's pushing his limits. Be firm when you discipline him. Do not be afraid. If he learns that this behavior works, you'll be reinforcing it.
If he's really coming at you nasty and mean, say ah,ah, sharply (or whatever term you use for discipline) to snap him out of it, pick him up immediately (but gently) and lay him on his side. Hold him down until he relaxes and stops fighting you. Do not talk to him or use his name until after he relaxes. He may give out a heavy sigh. Be careful to secure his head, butt and shoulders, so he doesn't hurt himself. It may take a minute or two.
Your tone must equal or exceed his level of excitement, or this will not work. After he relaxes and becomes calm, slowly remove your hands. You can pet and talk to him when he is calm.
If it doesn't work the first time, wait til he throws another tantrum and try again. Dogs live in the moment. You cannot correct something unless it is occuring right in front of you, he will not remember what he did 2 minutes ago.
If he keeps wriggling while you're holding him down, try imitating his mom and do a fierce growl. That will get his attention, until he learns English.
This is teaching him that his out of control, nasty behavior will not be tolerated, and that you are the Alpha. He really just needs to know that you are the boss. You do need to get this under control while he's young, or you'll end up with a nasty dog. If you don't feel comfortable doing this, hire a professional trainer. This behavior needs to stop now.
If you feel you are successful, but the behavior continues, have your vet check him for an underlying medical reason.
