After my chocolate lab died last year of cancer at 7years old and very suddenly, I did research into everything. The first thing I came up with was his food. We got a golden lab last September and the food we feed her is called N.O.W. It is made in BC Canada and contains no ethoxyquin, bha, bht. It is grain free and 100% render free. Bella loves it. The web site for this food is www.petcurean.com If you love your dog check it out.
