I have used Holistic Blend in the past and have found it to be a very good food, especially when they replaced the synthetic vitamin k supplement with the more natural k1.I am using another food now just because I don't have to mail order it as I did Holistic Blend.
The real concern should be providing the best nutrition possible for your dog and for me, it's not feeding just kibble. I feed mainly a raw frozen diet and mix some kibble in for the crunch and as a backup for any vitamins that the raw frozen lacks. I don't find that mixing kibble with raw frozen meats is a problem and my 1 year old loves it.
I know that this is primarily a kibble board but the interest should be in overall good nutrition, not arguing about what kibble has more meat or may give a shiny coat.
