I started my 9 dogs on NutriThrive because the value of food in assuring health is something i have studied for years. My dogs range in age from 3 to 10, and from small (10 pounds) to giant (125 pounds). Because i could not afford high end premium dog food but wanted to assure my dogs got the nutrients necessary for them to thrive, i selected NutriThrive. All are in great health, with georgeous coats, bright eyes and wagging tails. Just as I supplement my diet daily with vital nutrients, i supplement theirs, and the sucess of this formula is undeniable.
