Dog has recently started licking and eating dirt?

Sarah, you first need to get your dog to the vet for a complete check up with blood work up. Rule out any medical problems. What food is your dog eating at the present time? Grocery brand foods are not nutritious enough for him. Innova is an excellent choice of food. There are other great foods out there. Stay away from: Corn, Wheat, Soy, By-Products, Sorgum, Beet Pulp. Brown rice is better than white rice. Stay away from BHA and BHT.
