I never knew small dogs were capable of drooling until I met Scraps! Every foster I've had, I've been able to teach them tricks easily with a little food motivation. Scraps is another story. He has bad LP so he can't really sit like a normal dog would. So there goes many of the basic tricks, sit, shake, lay down, beg, etc. I tried a sit a while back, all he did was make a face like this
and then a big slime drool loogey started dripping out. Yuck! So now his trick is "do googly eyes", and then he gets a treat LOL.
This morning while eating breakfast, he was watching bf eat, and afterwards found a small wet puddle where he was standing.
Ewwww
So does your yorkie drool too?
