We feed ours a completely grain free diet. She began her life on James Well Beloved till about 3 months at which point we switched her over to absoutely grain free.
Mornings and afternoons - Milies Wolfheart dry kibble - 70% fish/meat content and the rest veg, no grains.
Dinners - Homemade - tripe, mince, liver (80%) boiled with carrots, couregettes, blueberries, cranberries, peas (20%)- make it once a week, lasts 7-8 dinners, costs £2 for the whole week's worth of meals. The tripe and mince is dirt cheap from natures menu and liver is peanuts!
She has excellent hard, firm, non smelly easy to pick up poop, no skin issues, is very easy to train and brainy, and loves her food!
