Troy Plaque Off is a daily dental powder for dogs, designed to reduce plaque and tartar build-up when added to food. It uses a seaweed-based active ingredient rather than brushing or chews, making it a low-effort addition to a dog's routine.

The active ingredient is Ascophyllum nodosum, a specific seaweed that works systemically — absorbed through digestion and then present in saliva, where it softens existing tartar and inhibits new formation. It also targets the bacteria associated with bad breath and gingivitis. Available in 50g and 180g sizes.

Dogs that resist toothbrushing are the obvious candidate here. The powder mixes into regular food without altering flavour noticeably, so compliance tends to be straightforward even for fussy eaters.
