Teaching Auggie to smile

I’ve decided it would be incredibly handy to teach Auggie to smile on command. Sometimes in the face of treats Auggie becomes SERIOUS DOG and doesn’t give me a smile… so if I’m trying to pose him and I have treats on me while I do this, I get SERIOUS AUGGIE IS SERIOUS photos instead of a normal goofy looking Auggie. Therefore, if I can be holding a treat and tell Auggie “smile!” and he will smile, I will get PERFECT pictures!! It’s genius, you see.

Except I forgot that my dog is an idiot and while trying to teach him a new trick he immediately begins offering up every single trick he already knows, or other things we’ve been working on. Like I’ve been working on cop-cop with him on and off for ages, so when doing heeling work, he attempts to get between my legs and stand on my feet. Or when trying to work on a down-stay, he likes to roll over.

The last trick I worked on with Auggie was teaching him to speak. I figured teaching smile would start rather the same, where I would click/treat any movement of the mouth, then start to narrow it down to the kind of open mouth expression I wanted. This was not a bad plan.
Except, again, I forgot that my dog is an idiot.
Therefore, this time, Auggie decided that I must want him to ROLL OVER WHILE BARKING.

Why, Auggie? Why? This is why I do things like buy a yellow submarine costume and put you in it.
