inadequate balance of nutrients and improper ratios of food types will all result in poor health of your dog. Each source is dependent on other, complementary sources to be absorbed by the dog and used for cell metabolism, growth and daily energy requirements. This is why balance and correct ratios are important.
For example, let’s look at the relationship between calcium, phosphorus and vitamin D. Without vitamin D, calcium cannot be absorbed properly, even if there is plenty in the diet. Along with calcium, phosphorus is required to build strong bones. In a dog, the best ratio of these minerals is 13 : 10 (calcium : phosphorus). Overall quantities in the diet should total 0.8% for calcium and 0.6% for phosphorus.
