It can be so funny to have a pet, like the one of the images that is used to ask for what he wants, using its own language.
In the box on the table there was a slice of pizza left and as you can see in his eyes, he would like very much to have it. Mistress pretends to not understand what the dog wants.
His reaction is priceless and makes the day of everyone who sees him. We can see how brave he is, waiting for the approval of the woman.
