  • Scientists have developed a new molasses-derived oral spray aimed at reducing bad breath and harmful mouth bacteria in dogs.
  • The low-cost treatment, made from polyphenols found in sugarcane molasses, was tested on 10 healthy pet dogs experiencing halitosis.
  • The study found that the spray significantly reduced the levels of bad-smelling compounds, such as esters, amines, and aldehydes, in the dogs' saliva.
  • Daily application of the spray over 30 days also led to a notable decrease in odour-causing bacteria, including Porphyromonas and Fusobacterium.
