What is the best thing to clean dogs teeth with?

Brush your dog's teeth regularly. You should keep brushing your dog's teeth as part of a regular grooming routine. Buy a dog toothpaste - human ones aren't suitable. You can use a special dog toothbrush that goes over your finger to brush their teeth, but if you don't have one then a child-sized toothbrush is fine. Dental chews and treats are also a good way of helping to keep your dog's teeth clean. Dry dog food may have the added benefit of exercising their chewing muscles and provide a mild cleaning effect on the teeth. Raw, meaty bones may be a tasty treat for your dog and do help clean teeth. Ask your vet first - before you start cleaning your dog's teeth, it's always best to ask your vet to show you the best way to do this.
