Thought I would post an update and a THANK YOU to everyone who offered advice on my naughty teenager :D Huge improvement in less than a month, no naughty posturing and no grumbling :) He has, this last week, been allowed to mix with a couple of unknown entire males (after I had checked with their owner) and he greeted them politely and then came straight away when told to (he got treated then was released to play chase with the younger one ) Obviously its an ongoing training project but im pleased at how quickly he has accepted the new rules which are now in place :D

Great news! Good to hear your hard work is paying off :)

If only fixing our obedience was as easy lol :D
