Hi AK-
While it probably isn’t crucial at this point to keep the calcium percentage that low due to the fact that your pup is 10 months old and has done a lot of her growing already, but it sure wouldn’t hurt just to be safe.
The Nature’s Variety Instinct Raw Boost Formula that you originally wanted to use should be appropriate if you want to give it a go. Also, Fromm Gold Lg Br Puppy, Orijen Lg Br Puppy, Wellness Core, Horizon Complete Lg Br Pup and Nutrisource Lg Br Pup are also some ideas to check out.
My large breed pups are now 4 1/2 years old. LOL! I feed them mostly 4 star foods and add canned or fresh meal mixers to their meals and they are doing great! Just remember, you don’t have to stick with one food forever. It doesn’t have to be a life long decision. If it doesn’t work, try something else! Best of luck.
