To expand on what Haley said (which is well said) the reasons for the proportions she gave s because they provide a dog with optimal nutrition and it avoids mineral deficiencies and imbalances.
One of the critical issues in canine nutrition is hitting near the target ratio of 1.2 : 1 for calcium : phosphorus.
Feeding soft edible bone at 10% (with an 80 meat meal) ensures one is in the proper target range.
The organs are powerhouse supplies for other vitamins and minerals. Regular feeding at 10% (5%/5%) is nutritionally necessary.
Otherwise, (as Haley said) you’d need to balance the meals with calcium and vitamin supplementation. Not a solution I’d choose unless I had no alternative.
Just feeding meat alone would eventually lead to nutritional imbalances and health problems.
I’d cut the veggies. They are a negative in a balanced canine diet.
