Hi Mooki,
On a whole your pup is actually a fairly well behaved 'monster' !
It's very natural for dogs to get excited at walk time, but I think you are doing the right thing by walking away and ignoring him when he gets 'too' excited, and with a bit of patience he will learn just like the other dogs mentioned in this thread have done!
I think the other human who takes him on walks also needs to be more vigilant in this regard. Instead of just putting on his lead despite the jumping, he really needs to wait for puppy to be settled before putting his strap on.
Oh... Me and Axel love it when you take him out for walks too.. We eat all his dog food, play with his toys and mess up his bed!
Regards,
Nimmo
