We have used Advance, Hills, Royal Canin, Natural Balance and Purina Pro Plan.
For Collies and Greys the Advance wins hands down. Superb coats. bright eyes, lots of energy. On the others the Greys drop weight and the Collies just seem lack lustre in temperament and looks.
As someone said earlier - different things suit different dogs - but for us - Advance, no question.
I then suppliment it with rice or pasta, and sardines or tuna or chicken necks or beef off cuts, and veges or fruit.
They are very well fed dogs!!
I have three on Active (designed for working dogs) and one who carries a little weight on the Adult chicken.
