The pooch on the Dog with Toothbrush Visa Gift Card could be reminding you to brush your teeth, but more likely he’s asking you to brush his. Veterinarians estimate that 85% of dogs age five and older have periodontal (gum) disease. It’s caused when food and bacteria form plaque and tartar that enflames the gums. Tooth-cleaning chew toys help alleviate the problem, but it’s still good to give doggie frequent brushing with toothpaste made for dogs.
