Most breed experts recommend that puppies start on
an adult dog food formulation with a protein percentage no higher than 26 percent, and a calcium / phosphorous ratio of approx. 1.2:1.
Regardless of their quality, commercial
dog foods are available in different
formulations, suitable for different life stages like growth,
adult maintenance, pregnancy and lactation, and in three main different forms: wet (or canned), dry and semi-moist.
