 | |  | | I gave Sassy 11 mg phosphorus per pound which is about half the requirement - that was extremely low. Phosphorus is an essential nutrient and you don't want to reduce it too far. 38 pound Max gets 800mg which comes to 21mg per pound and is his requirement. The recipe gives Max about 800mg phosphorus per 600 calories.
I estimated the dogs needed 20 calories per pound, don't know where I found that handy starting point. It is probably low for most dogs but when switching to new food less is better anyway. Then I fed more or less depending on body condition. Sassy ended up needing 1000 calories or 25 calories per pound and Max needs 600 calories or 15 calories per pound. You already know how many calories work for Bella, then the spreadsheet gives you how much phosphorus she needs, work from that. If the calories she needs in the recipe I make provides the amount of calcium and phosphorus she needs then you are good to go. If not use more bony ground and less egg shell for more phosphate or bone free meat and more egg shell for less phosphate. If you want to reduce her phosphorus to less than the NRC requirement all you need to do is feed her bone free ground with 1/2 tsp of egg shell per pound of meat. I know it is more expensive but that might actually be the way to go for her and use the bony grinds for the other dogs.
Very very rough example. If I just gave Max 90% lean hamburger he would need to eat about 12 ounces to get 600 calories. Each once has about 51mg of phosphorus. If I mixed 1/2 tsp of egg shell into that he would get 900 mg of calcium and 620mg of phosphorus which is 78% of his phosphorus requirement. If he needed to watch his phosphorus that would be a logical starting point.
See the raw feeding spreadsheet for how much of what she needs as a healthy dog, it is linked in Sedona's thread.

If a dog is allergic to the meat then the organs and bones are likely a bad idea. Oddly some dogs can eat eggs even if they are allergic to chicken but some cannot even eat the egg shell. Some dogs are so reactive to corn that they must eat grass fed meats!
So look for venison, moose, duck or goose liver for her. Since it is such a tiny part of the diet even if it costs the earth it isn't so bad and if pushed to the wall it is possible to use supplements and choose veggies like potato maybe to make up for no liver. I am looking for copper in the liver, pork and chicken liver have quite low copper content. Just looked at ND. Oysters have a lot of copper too. They are real powerhouses of nutrients, you can use them for zinc and vitamins Bs too. Copper is tricky, it is necessary but in very small amounts and too much isn't a good thing. |  |  | |  |
