Hello, This 5 X 7 is in oil painted on a canvas panel. This is one of my grand dogs, I took the photo a while back and my grandson wanted me to paint it. I take care of my grandson a few hours in the afternoon four days a week, so while he naps it nice to paint something small and quick. Fun to paint and I think it came out looking like Benny, that was what I hoped for, lol. Have a great day!
