Hi, I'm using skinners ruff and ready at the moment, but I have it on very good authority that the ruff and ready, and field and trial museli, are one of the same! the field and trial is actually cheaper as it's vat zero rated.
I'm using it for my two Labs, 11 months and 2 years old, and am very pleased with it. The dogs enjoy it, look great and output is good. I have found that feeding it slightly moistened has helped to slow their eating down, as both dogs used to bolt down ordinary nuggets and make themselves sick.
Overall, I am very happy with it, and having tried various different foods, think I shall be sticking with skinners.
