A dog toothbrush is a specially designed tool for cleaning a dog's teeth and gums. 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 prevent dental issues such as plaque buildup and gum disease. Regular brushing can contribute to better overall health for dogs, as dental problems can lead to more serious conditions. It's important to use toothpaste formulated for dogs, as human toothpaste can be harmful to them.
