I have heard many "prey model" aficionados claim 80% meat, 10% bone, 10% organs as the ideal ratio, as this is supposed to be the ratio of a whole carcass, but since I have never actually seen the figures I don't know if this is true (or just often-repeated hearsay).
To be perfectly honest, I personally don't really put a lot of time trying to figure out exact ratios like this.
However, just looking at my diet and giving a rough estimate, if eggs are to be classified as meat, I would say I feed approximately 55% meat, 15% bone, 10% organ meat, 10% vegetable mix, and 10% extra oils.

PS: If your dog is straining too hard to take a rock-hard dump you're feeding too much bone ... and if the poop is too watery/sticky you're not feeding enough bone. However, I like to see them strain a little bit, because 1) it means they're also expressing their anal glands (which will never get impacted) and 2) I won't have to be scrubbing any shit off of my above-ground pens![]()
