When changing your senior dog or cat to a raw diet, make sure to choose a high quality protein. Studies show dogs and cats need to consume more protein as they get older. This will help them maintain healthy lean muscle mass and even build more muscle and maintain proper organ and immune function.
Your dog or cat needs a high quality meat that has been processed. This will help keep the nutrients intact. The protein you find in most processed pet foods is rendered. This puts a strain on your pet's organs, specifically their kidneys and liver. By the time your pet is older, if they've been eating processed foods for years. their organs have been working too hard. They no longer do their job as well as they could. That's why a raw diet is better. The sooner you get your pet onto a raw diet, the better.
A raw, balanced diet has all the components of a preventative diet that seniors need. As we all know, "We are what we eat" and that goes for our pets too. High quality raw diets include a meat-based protein source. As well as, calcium from whole bones, organ meat, greens, probiotics(think yogurt), Omega 3 fatty acids, herbs and superfoods.
