you can feed natural instinct but i'm not a huge fan of always giving minced food. one of the things i like about raw feeding is giving the dog a bit of a chew so that she doesn't eat her food in 2.5 seconds keeping her occupied and me feeling that she's had a proper amount of food and hence not over feeding her.
Six month old field bred lab so not a huge one but then not as slight as some of those i've seen.
b/fast lamb bone or chickens legs or green tripe (sheep or beef).
tea beef cheek, heart (considered muscle meat), kidney, small bits of liver, fish heads, different bits of chicken, tongue. again tripe. sardines in tomato sauce, the odd egg. in season, pheasant and rabbit if i can get other people to do the skinning etc.
things I don't feed
vegetables, fruit (personally, not sure that this is all that useful if you keep the tripe amount up. i can get lots of paunches and all that chopping etc is too much like hard work. If I've fed things like natural instinct the eg just comes out the other end in exactly the same form. i'm assured that the goodness has stayed in the dog but you don't get it carrot peppered poo with tripe.
lamb necks lamb knuckle bones very meaty lamb bones (makes dog sick but she does love them)
weight bearing big animal bones eg cow leg bones. am told there's a potential of it cracking her teeth
cooked bones
other things i feed
salmon oil - 2 x tsps per day to keep her coat shiny put on her food
liver cake treats
i feed her around 800g of food a day but i don't measure it too carefully.
hope this helps. honestly don't worry - it just sounds so much more complicated than it actually is. A chest freezer would be a good purchase if you don't have one.
