What you need, Dyan, is a recipe that includes some carbs. Probably white rice for the urps you are getting.
I cook for seven dogs. Well, I did and tomorrow my wonderful husband is going to do it under my eye so we can get going on this again!
Anyway, that's certainly as much as, if not more food, than your one Dane pup can eat. We do it in two hours each week.
Here's how it goes. I put on pots of oatmeal for the oatmeal eaters (two dogs and Maggie eats a tiny bit). A pot of rice goes on for Lynn (she's the one with the touchy tummy). I put potatoes in the oven (actually I did that much earlier in the day) - so many white, so many sweet. The veggies are chopped and go on the steamer, along with the fruit - carrots, zucchini, apples, jicama.
While all that is cooking I set out seven bowls. I get out the food processor. I take out the potatoes and slice and process them and divide them amongst the bowls. I also process parsley and cans of fish likewise. The fish doesn't need it but I found it makes everything easier to mix.
Now the grains are usually done and I crack the eggs into the hot pots of rice and oatmeal and let that sit for a few minutes. This will allow the rice/oatmeal to cool faster and the whites in the eggs will set but leave the yolk runny.
I then start processing the fruits and veggies. I usually do this by dog or I get confused, because up to now everything has been pretty much the same, but from now on the recipes differ. Lynn gets carrots but the boys get sweet potatoes and zukes, for instance. Everyone gets apples and jicama for digestive health. And that's it - I don't go for variety any more on the basic recipe.
When that's done, usually the grains are still not cool enough to work with, so I start slicing up meat. Each dog gets beef heart and pork kidney. I cut up each dog's portion and set it on small prep trays. Out of the reach of the dogs. lol
Now usually the grains are done. I fill each dog's bowl, mix, and then call Patrick because I really hate the next part. He starts labeling baggies and turning them, and I fill them and set them up in a box. Then I drop the meat in on top of that. Then Patrick closes up the bags.
When we are done, we have seven little rows of seven bags, per dog. That's breakfast. These bags go in the door of our commercial freezer. They could easily fit in a regular freezer, but nothing much else would. Even Lulu's breakfast (she's 100 pounds) is still only a quart bag full.
The secret to the boney part of their meals is that they are not portioned out daily, but weekly. So one dog gets, say, 32 oz of chicken quarters, 48 oz of turkey necks, and 16 oz of pork rib - while another dog gets 24 oz chicken quarters, 8 oz pork rib, and four chicken feet. The gallon bags are prepared with the dog's name and the portion of food and type, and often I only purchase one type of food that week - ribs or quarters - because it was on sale.
Then I simply portion that one food out and I've got the dogs covered on that point for a few weeks to come. It's much easier to sit and portion out the same type of food over and over in a single sitting, than it is to try to figure out all the different types and portions each week, week, after week.
If you wanted to simplify this part of your dog's diet, you could simply purchase boneless meat and as several have mentioned, add calcium. You can use a supplement, or you can use a human grade bone meal, or you can use eggshell. One of my recipes (the one for Ted), has eggshell in it. I'm fortunate in that I can use my own duck eggs so I don't have to mess with washing, but there's no harm in using the shell from commercial eggs. I do mine up when I get enough shells, put the powder in a little baggie, and store it in the freezer.
