Support your dog’s dental health with ease with OraVet Dental Care Hygiene Chews for Dogs, 25 - 50 lbs. When your canine companion sinks his teeth into one of these once-a-day chews, it will help scrub away plaque and tartar buildup. The natural chewing process removes existing plaque through mechanical action, while releasing a protective agent to prevent future buildup. These chews contain delmopinol, which coats the teeth, creating a barrier against the bacteria that lead to the formation of plaque, tartar and bad breath—delmopinol is also used in human dental products! Your furry friend’s teeth will sparkle and shine in no time!
