How about gifting him a subscription to a dog trainers' magazine? This will motivate him to stay updated with the latest training methods and information.
Alternatively, you can also consider getting him a dog training book or DVD set that focuses on a specific training technique he wants to learn more about.
If your boyfriend loves spending time with his furry friend, a personalized dog tag with his dog's name and your boyfriend's contact details engraved or embossed onto it would also be a thoughtful gift.
You could also consider booking a session with a professional dog trainer, letting your boyfriend participate with his dog. This could be an opportunity for him to learn new skills, and would help strengthen the bond between him and his K9 companion.
Or you can get him a star map with the date when he was born.
