I adopted a 14 year old mini poodle from a rescue in Nov. of 2013. Since his owner had died, there was no information about his eating habits H e was having digestive problems and my vet was trying all kinds of medications. When I found this product he loved it immediately. I was thrilled. Recently before having oral surgery for some teeth that had to be removed, the vet was so surprised that his blood work came back looking like that of a much younger dog!! He had been eating Freshpet Select for 6 months at this time. She was amazed at his results I know you cannot make any claims about this but I have seen the improvement in his eyes and coat, energy level and even his temperment because there is no more tummy issues. Thank you for this product!
