Cookie is a nine year old Labrador from Serbia. Cookie switched to raw at 6 and improved after being on kibble since birth. During that time, he had two ACL injuries (one surgically repaired), and was diagnosed with mild ED at age 6. He would limp on and off on that leg until we switched on raw. He didn’t have other major health issues while on kibble. The changes I’ve notices after switching to raw: no more joint issues, a nice muscle tone, normal levels of calcium and phosphorus in the blood (they were off on kibble), normal liver levels (also off while on kibble).

This show that it is never too late to start you pet on a raw food diet.
