Every year, more than 8 million tons of pet food are manufactured under 15,000 different brand names. How do you ever decide what’s best for your pet? Giving food that’s closest to their natural diet is the best option. But read the labels carefully, because the ingredient lists can be confusing and misleading. And many pet foods are not sufficient to keep your pet healthy. If your pet’s food is deficient in nutrients, as many commercial dog foods are, we recommend giving your pet a daily multivitamin.
