I certainly would not give this to my animal. As much as we love our dogs, we cannot keep them here longer than God gave them to live. Dogs lifespan is what it is, and it won't change- Just like our lifespan is limited. Unfortunately our loved animals are not on this earth as long as we'd like. However, dogs live a life of no regrets and unconditional love, and they die with happiness. No reason to keep them here longer unnaturally for our selfish reasons.

A good diet, enough exercise, and a well cared for dog will live as long as it is natural to!
