I have fed raw since my dogs were pups. I don't ever weigh out the portions. I prefer to just see what works, keep an eye on their condition and adjust from there. Each dog is different. Mine get a mix of rabbit,tripe, beef trim, lamb ribs, chicken carcass, mackerel, any off cuts. They also get any scraps. Depends what's in the freezer really. I just try and mix it up and vary it a bit. ATB
