What happened

A smelly dog breath breakthrough: Plant-based spray tackles odor and harmful oral microbes Gaby Clark Scientific Editor Robert Egan Associate Editor Pet owners love their dogs but may not always love the smell of their breath.

Why it matters

Because this bad odor can signal oral disease, veterinary clinics will prescribe daily toothbrushing, antibiotics, or chemical rinses as treatment.

Common ground

Now, researchers reporting in the Journal of Agricultural and Food Chemistry propose an alternative: polyphenols from molasses.
