I am trying!
I say "go potty." My pug knows that phrase, along with, the infamous: TREAT, wanna treat? haha. And "sit, stay, down, paw, eat, drink, kissy kiss.
And I always cheer on Mango when he does something good...he likes that. It's like.....he knows he's so darn cute, that he knows he can do everything wrong in the world, and know I would still love him! I have a pee pad everywhere I go when I'm in the house...so far, no use.
