Oh I'm sorry, I had to laugh.....Even my lovable old man Samson does that still at the ripe old age of 10....Boxers are late bloomers, so like Tootsie said, about the time they hit the "teens" people get frustrated and give up, hence so many in the shelters....It does take patience, oh boy does it....There have been times I would cheerfully pull my hair out to refrain from doing what I really would like to do......It very much is a battle of wills, esp as you are both males..That's one of the issues I am dealing with with Angel..We are both strong willed, hard headed...well you get the picture.....
The lead is an excellent idea, by the way..Great way to work with him to learn to "come" when you call...Use his name over and over again...As for treats, mine have loved everything I have ever gotten, but I think I also used those Authority treats in class and Samson loved them..Trial and error there...I actually bake my own cookies now for mine, so no more store bought treats...
Take a deep breath, repeat to your self, this is just a phase, it will pass, and if you drink, have a nice tall cold one...Lol....Can't wait to meet you both at the next meetup..He sounds like a character
