This wooden Rat Terrier dog puzzle is 7 1/4" long, 6 3/4" tall, 3/4" thick, it has 12 pieces, with the base it stands 7 1/2" Tall. The base keeps the puzzle from falling over, which makes it a nice way to display the puzzle, we are the only ones to do a base with the puzzle. I use oak wood for the puzzle, this handmade wooden dog puzzle would make a great gift for that dog lover. all our wooden puzzles and toys are made here in our shop in Virginia.
