This thread seems pointless and it appears to me that you don't have much of anything to say, but want to post crap in the tavern anyway just to be "that guy".

Get over it. You should have been more aware of your surroundings and noticed that your pooch was nicking your Mittagessen! You can't blame a simple animal that acts on instinct and impulse for your carelessness. Forgive and forget.
My late dog Noel (R.I.P) stole a toast from me one morning and while I was chasing him, he growled at me. I started laughing, thinking he was probably telling me that I left it unsupervised so it was my fault.
Now, then Angel of so-called War; if a dog ate your sandwitch, this means that, unless you followed R2's reasoning, you yourself did not eat said sandwitch. How, then... do you assert that the sandwitch was good?
I put it to you that you ate the sandwitch and attempted to divert suspicion from you by accusing the dog of the same crime.
