I'm still not sure about that calculator, lol. I put in several AAFCO tested foods and it STILL told me some of the basic micronutrients were "Probably" or "Possibly" deficient.
Anyway, clearly there's a lack in several things that would make me nervous in a senior dog. Vitamin E and selenium are vital antioxidants. The B vitamins are needed for mental, digestive, and nervous function. And calcium IS needed to keep the dog active and for many other functions including muscle contraction (both involuntary and voluntary) and nervous transmission.
It's super easy to add the eggshell from the eggs to the diet to bring the balance of calcium up to a proper amount. Thin-ness could be muscle atrophy in a senior dog, rather than weight loss. I struggled for years with MY saying Ben was too skinny, while the vet said he was fine, since his weight looked the same. He was losing muscle mass, something to do with the thyroid problem. Once we got on top of that, he filled out nicely, though he actually only gained a couple pounds.
Try increasing the meat somewhat (decrease the rice accordingly), while making sure you add calcium and antioxidants. If this is a diet for renal support, increase the egg (check with your vet and cook the whites). Also, consider adding a vitamin B complex supplement - either a simple formulation you can get at any drug store, or, my preference, a formulation balanced especially for senior dogs and cats - "Cholodin".
Finally, I'd definitely go for a fish-based OFA supplement, for a lab. Preferably cold water fish body oil. Border Collies hail from the same part of the planet (northern Atlantic) and also seem to have high requirements for fish-based OFAs. In their homeland they have a very fishy diet and so did many working hunting retrievers.
Good luck!!
