what percent protein do dogs need
These dogs can require between 25 and 35 percent protein in their food. Female dogs nursing a litter also require 28 percent or more protein. Elderly dogs may require lower protein percentages if they have kidney or liver damage.
Most adult dogs have only moderate energy requirements. Because they are no longer growing and do not need to perform a lot of muscular repair or development, they require only about 18 percent protein in their food. However, adult dogs require at least this amount to maintain themselves in good repair and good health.
