Molasses polyphenol spray shows early promise for canine halitosis

Researchers reporting in the Journal of Agricultural and Food Chemistry say a mouth spray made with sugar cane molasses polyphenols reduced bad breath, odor-related compounds, and some oral bacteria in 10 dogs with halitosis. In the ACS press release published May 18, 2026, the team said trained evaluators found breath odor was negligible one hour after application, and after 30 days of daily use, saliva samples showed lower levels of certain odor-associated compounds and lower proportions of Porphyromonas and Fusobacterium, two genera linked to oral malodor and periodontal disease.

Why it matters: For veterinary professionals, the study adds to a growing body of work on adjunctive oral-care products for dogs, especially for pet parents who struggle with daily tooth brushing. But the evidence here is still early: the trial was small, involved healthy dogs with smelly breath, and was presented as a proof-of-concept rather than a replacement for standard dental care. Current AAHA and WSAVA guidance still centers prevention on regular dental exams, professional assessment and treatment, and consistent home care, particularly tooth brushing. (acs.org)

What to watch: The next step is whether larger, controlled studies show that plant-derived sprays can improve clinical dental outcomes, not just breath odor and salivary markers. (pubs.acs.org)
