A dog toothbrush is a specially designed tool for cleaning a dog's teeth. Unlike regular toothbrushes, they often have softer bristles and unique shapes to accommodate a dog's mouth. Many come with angled heads or dual-ended designs to make brushing easier for pet owners. Using a dog toothbrush helps maintain dental hygiene by removing plaque and preventing gum disease. Regular brushing can lead to fresher breath and healthier teeth, contributing to a dog's overall well-being. It's important to use toothpaste formulated for dogs, as human toothpaste can be harmful to them.
