My 4 year old beardie loves this, its the only kibble he'll eat. I'm aware he should be on adult but he just won't touch it.
My 3 year old dog prefers this to the adult version, and as he's a very picky eater I've kept him on it - sometimes its all he will eat! He even prefers this - at times - to cooked chicken, lamb or beef ... so it must be exceptional!
My dog loves this and its reasonably priced. He also loves the marrow bones and beef ribs.
