There has been a big push in the veterinary world in recent years to try and increase dental hygiene in pets. Vets are encouraging owners more and more to make brushing their dog or cat’s teeth, to remove plaque build-up, part of the daily routine, like you would walking or feeding them. Companies have, of course, jumped on this trend, and developed products designed to improve dental hygiene, including pet toothbrushes, toothpaste, and now ‘doggy mouthwash’. Doggy mouthwash is added to dog and cat water bowls to ‘help fight your pet’s bad breath’. The main ingredients, chlorhexidine and xylitol, are supposed to kill bacteria and reduce plaque, with the advantage being that the liquid can reach where traditional brushing might not. Anecdotal evidence and product reviews indicate these products do help reduce bad breath and keep teeth looking cleaner. However, there’s been a recent hubbub around the inclusion of xylitol in the ingredients.
