Answer 1

Have him checked out by the vet to make sure that the bad breath is not a sign of a more serious issue.  After that, try brushing their teeth regularly and giving them dental treats.  Bright Bites are a good one for you to try since they are designed to clean a dog's teeth and freshen their breath while they chew.
