More often than not, dog owners gravitate towards soft chew treats. While your pooch may appreciate them, they sometimes contribute to the bad breath issues.
This is because their consistency makes it easier to have them stuck between teeth or coating the teeth, hence resulting in plaque.
Therefore, you should consider throwing some hard treats into the mix to help with the breath issues whose abrasive properties result in mechanical cleaning of teeth.
These include bully chew treats and dog bones. Just find something that your dog will like. And the best part is that in addition to being awesome treats, they last very long.
