Hi, I'm kind of at a loss as to how to correct my basset's horrendous breath! Gus is 3 years old, I've brushed his teeth, taken him to the vet to check his gums and teeth and still no improvement. I've bought all of the recommended chew toys, and still nothing helps.I've even changed his diet. Is this a common problem? I have a few friends who have bassets and not a single one of them has this kind of breath. I'm stumped! Any help or hints would be greatly appreciated.
