We just love the image and Sundog has been part of our business name since 1998 when we went on a road trip and changed our company name to “Sundog Media“. We feel it was given to us by God as we were praying for a really cool name. 
And… years later after we named our boat “Sundog”, we were driving down the road and noticed in the rear view mirror that “SUNDOG” spelled backwards is “God n Us”. Pretty cool eh! O.K. I am not the type to play rock music backwards and get encrypted alien messages but you have to admit – it is pretty cool.
