A Cleveland-based biotech startup has invented a new medical device that fights oral bacteria linked to bad breath and gum disease in dogs – a health problem that affects 80% of our canine friends by the age of three. The device, called Zumby™, is disguised as a dog toy and uses a very small, safe and undetectable amount of electrical stimulation, known as micro-current technology, to eliminate harmful oral bacteria. In lab testing at Case Western Reserve University, micro-current technology eliminated 70-99% of harmful oral bacteria.
