I have a 15 year old Great Dane. FIFTEEN! According to my vet, he should be long gone. I have fed him Pedigree since day one. I know lots of people say "you need to buy Blue Buffalo or IAMS because giant breeds need better food". This is the only food that has not given him an upset tummy. I will continue to feed him, my 3 y/o Great Dane and my 4 y/o Doxie Pedigree! Kudos!!
