The plaque on your dog's teeth, if left untreated can turn into tartar. Tartar looks yellow or brown and can cause problems for your dog's gums. This can, in turn, make it difficult for them to eat and can lead to gum disease. The best way to reduce the build-up of plaque on your dog's teeth is to brush their teeth regularly using a special dog toothpaste and toothbrush. If your dog isn't a fan of having their teeth cleaned, then we also stock an additive for water that will keep their gums and teeth healthy. However, our dog-friendly toothpaste tastes great for them as well as freshening their breath so you may find it easier than you think to establish a teeth cleaning routine for your pooch.
