Well I'm rather a novice at raw feeding ... I've only been doing it for about a year now. But I will say this: my 8 month old pup has always had raw, she is bright, alert, happy, clever and growing at an alarming rate. She eats tripe, chicken, beef, fish, lamb, rabbit and the odd bowl of Petitts Working Dog once or twice a week, to which I add veg. I give her one capsule of Evening Primrose oil every morning. She also gets kidney, heart or liver once a week, plus a couple of raw eggs in the shell. My 2 year old greyhound gets the same. They're both thriving. I've worked with and lived with dog
