My 6 year old son loves dogman books and wanted this one. It says it's for ages 6+ but my 6 year old couldn't do it on his own at all and he can follow the Lego instructions which are for 8+. It didn't have step-by-step instructions. This includes folding and inserting flaps into slots based on printed numbers. I had to collect for my son. I'd say kids 9 and up can assemble this on their own, but kids under 9 will likely need help. Also, my son loves to play with it.
