1 wins and so does his pic

You should look at your dog and just be like "get your own peanut butter cookies >_>"

Dogs don't hold grudges! You seem VERY smart...

...I'm trying to fathom how you're aware that your dog is mad at you. Does he sit there and "e_e" at you? Perhaps you've been on shrooms? Acid? Maybe a little bit of Salvia? Hell, I've even known Klonopin to cause hallucinations. If it's none of that, then consider a psychiatric consult. It could be schizophrenia, or another hallucination/delusion/paranoid disorder

@29 or she has a good sense of humour

Why is it that I imagine this FML being written with assorted used syringes and empty pill packets scattered around the drooling OP?

I like the ones that give you minty breath and a shiny coat.
