You’ve just returned from the veterinarian’s ofﬁce and are completely overwhelmed—your beloved 10-year-old Dachshund, Cody, has been diagnosed with diabetes. Your veterinarian told you that Cody is very sick, and that if he doesn’t stay on the proper diet, he could die. You never realized how important your dog’s diet and weight were to his health. You think back on all those delicious dog treats you gave him and worry that your loving care may have somehow harmed him. You want to do everything right from this day forward, but don’t know where to start.
