Hey I appreciate you going thru the trouble of getting that information! When I looked originally for the Black gold,it was only sold in 1 store in Pa! Unfortunately it was way too far away. I did find something Ive started them on, and so far so good.But it wasnt easy b/c there are very limited locations around here that sell premium dog food and several of them I came to find,had shut down!I am using Natures Choice by nutro.Already just by mixing it the last couple of days,the dogs look shinnier.I cant belive it! But if I have any problems I will look into the other 2 brands,and thanks again!
