The health of your companions relies greatly on their diet. And like humans, animals prefer to eat foods they enjoy, they are easily bored with a repeated daily diet, and often need a variety of supplements depending on their state of health. The best diet is one approximating a natural diet in the wild. Dogs are mainly carnivores and cats are true carnivores, so a diet plan should keep this in mind.
Many guardians do not have the time or a lifestyle situation that would allow the time to home-prepare their companions' food. For these situations, I recommend buying a frozen, raw diet or a dehydrated raw diet, available from various sources. There may be a source in your area or you may have to locate one that sends frozen product via UPS or FedEx. You can feed some commercial dry food as part of a good diet, but keep the quantity to a minimum of the overall diet. It is important that raw or fresh food be included at least three times per week to give your companions the opportunity for the best health possible.
Currently, there are many good choices for healthy diets. Two foods that I am very familiar with and have fed my animals for years are Darwin's Pet Food (www.darwinspet.com) for both dogs and cats, and Big Dog Natural (www.bigdognatural.com) for dogs. Many guardians find this easier than shopping for premium food or use these in part of their overall diet. Call our office for instructions if you need help ordering these foods. Darwin's also has prescription, raw diets for certain disease conditions such as liver, kidney and cancer.
