I tried those dog puzzles 9 years ago and went on to other puzzles. They did not sell very well for me. I think they were called Woodimals by Jim Sweet. There were other designs besides dogs.
I now only carry some of the more popular breeds - dachshund, golden retriever, poodle, terrier, and lab. But NOT in the Woodimal style with the name built in. just stand up puzzles. I had to design the poodle and terrier puzzles and they are Pickens Puzzles originals.
