How about a customized leather dog training leash with his beloved dog's name on it? You could also consider getting him a dog training book that he could read during his spare time to learn new tips and tricks. If he has a particular breed of dog he loves, you could get him a carved wooden sculpture of that breed for his desk. Another idea is to enroll him in a weekend dog training course with a renowned dog trainer that he admires.
Or you can get him a star map with the date of your first kiss.
