Wet foods contain more water, which helps cleans the dog's mouth and reduce bad breath problems. 

Consider hydrating your dogs regularly by feeding them with wet food or adding wet toppers to your dog's dry food.

Probiotics can work wonders in your dog's stomach and dog's breath. 

This good bacteria can fend off the harmful bacteria present in the gut, thus causing the awful breath to go away.
