Linda, great to read about the beneficial effects on your old girl. Reducing carbs and increasing fat and protein is the dietary means of increasing energy and muscle building.
I’m not a bit surprised you are seeing benefits.
I have one quibble with the raw feeding approach you are using thus far. Too much bone. Way too much bone. The target percentage should be about 10%. You are probably pushing 28-30%. No done harm in the short term, that that much calcium to phosphorus will cause a mineral imbalance. You need to add more meat to this mix. Preferably that would include some red meat (beef heart is very nutritious and often inexpensive) and some fatty (cheap) pork (like leg or butt).
I’d also add beef kidney at 5% of total diet. The organs provide the vitamins. Supplements are unnecessary, but organs are critical.
If you make these adjustments you could stop the kibble.
I hope your dog feels better and better.
Bill
