Great! How about a custom jigsaw puzzle with a picture of your husband's favorite breed of dog in a historical setting?
Some options could be:
1) A jigsaw puzzle featuring a photo of a historic military dog that was crucial in a war he's interested in.
2) A puzzle with a picture of a famous historical figure and their dog, like George Washington and his dog, Sweetlips.
3) A puzzle featuring an iconic painting or photograph of a dog breed that he loves, such as a bloodhound depicted tracking down an infamous criminal in history.
You could even add a personal touch by including a special message on the box or a dedication on the back of the puzzle pieces once it's completed.
