Hi Rafferty - sorry I can't answer your question as I feed my dog the raw food diet (or BARF - biologically Appropriate Raw Food) as tinned dog food is approx. 78% water. He has lots of raw chicken carcasses and meaty bones (never, ever give cooked bones) plus raw fruit/veggies and most things I eat (again raw) all whizzed up in the blender and given over cooked brown rice/pasta or cooked potatoes. Hope you don't mind me recommending this instead of answering your question but maybe you'll agree with the diet if you check it out on line. Just google in BARF diet.
