commission portraits

I have heard that there are many different ways to get commission portrait. Some of the better versions are done in pop art style. I am thinking of getting a photo on canvas for my home and have seen photo on canvas prints that have a good Lichtenstein flavour. I want the picture to be their pet dog and wondered if anybody thought that a pop art of a German Shepherd was too much? I don't think so but then that's just me.
