Can you help me decide which size canvas I should select that would complement the picture I'm sending you?

That's a tough one. There are many factors to take into consideration. First off, how many pets do you want to display in the painting, portrait or full body and just what size would complement the space you are looking to hang it at. 

What seems to work for a lot of my clients, is they will cut out some of these various sizes out of butcher paper or cardboard and hold them up to the wall to get an idea of how that size might blend in to the surrounding area.
