I'm not sure if there is really any one dog food that helps with bad breath. Basic oral care could help though. I brush Sasha's teeth at least every other day, use Petzlife Oral Care gel on the days I don't brush & she also gets holistic dental treats usually every other day. To me, her teeth are in better condition than what they probably would look like if I didn't care for them like I do. Just a suggestion.
