Iggy, Scott, gave his explanation. I think he is right - it is mainly the "cuteness" factor. People do not buy them to actually use as a puzzle. They are like clocks and other items, simply decorations that people buy to display on their desk, a shelf, etc. They sell for the same reason your clocks and other things sell with different "themes" to them. The item or object has "meaning" to that person - their dog. They make a great gift for that person in your life who has that dog, for as Iggy said most people have a dog or know someone who has a dog that they love and adore. While I don't sell them, i have made several and given them away as gifts. They are always immediately loved for what they are - an image of their type of dog. The fact that it is a puzzle, just gives it a 2nd "cool" - and it might be put together once but then is displayed on a shelf. Because of that, I considered making them as a "whole" object rather than a puzzle but I didn't really like how the one i tried work. The extra "puzzle" cuts add that extra bit of detail that makes it look better on the whole. I figured you could do part of those cuts so plan to try again and see. I know Kevin is doing some as ornaments that are not cut out as puzzles for example. I think you might find that dog clocks - might be a good seller as well.
