Prescription dog diets first started in the early 1900s and became more popular as World War II began and meat was rationed. Dogs' diets were traditionally made up mostly of meat, because people thought they were strict carnivores, Soggy Paws explained. But these prescription diets became successful as people saw the impact of their nutrient-rich ingredients. These primitive prescription diets included many of the ingredients that people think of in modern dog food, including fish, soy, egg protein and other healthy meatless ingredients.Over the years, prescription pet food has evolved to the point where it's specialized to deal with a number of common canine health problems. Some have been formulated to reduce stomach irritation that can cause diarrhea or constipation, while others work to soothe more severe problems, such as colitis, skin conditions, dental health, diabetes, heart problems, pancreatic disease, obesity or allergies.Take a look at some of the most popular prescription pet food, their uses and the best prices available.Hill's Prescription Diet Dog k/d Dry Food
