What is Hill’s Pet Nutrition Pet Food?

Hill’s pet food was designed with a simple mission: to enrich the lives of pets and to help lengthen the special relationship between pets and the people who love them. In the late 1930s, exceptional vet, Dr. Mark Morris, developed a brand new dog food with the intention of helping a seeing-eye dog suffering from kidney failure. Together with his wife, Lousie, Dr. Morris created a dog food that was low in salt, yet high in flavour and nutrition value. This food became Hill's Prescription Diet k/d™, and paved the way for a vast brand of both cat and dog food designed with your pet's nutritional health in mind. Now, Hill’s is one of the top vet recommended pet foods and the company prides itself on being a leader in predictive biology and using only science-led ingredients in its food.

This food was a game changer for one of my Persian boys, and stopped the constant scratching and pulling out of fur. It was so successful that I could start to show him again, with great success.
