Dogs lose a lot of vitamins and minerals each day through play, exercise, and normal daily activities; dog vitamins are the answer to this problem. Whether your dog takes a multivitamin or a specific set of vitamins, it is important your beloved pet gets them from you daily. The B group of vitamins for dogs helps keep your dog's muscles, skin, and blood healthy, while vitamin D helps maintain healthy bones and teeth. Making sure your dog gets enough vitamin A, C, and K is also critical. Once you get your dog on daily dog vitamins, you will notice improvements in his or her coat, energy level and teeth, and your pet's chances of developing heart problems will decrease.
