Learn about puppy nutrition with information on everything from age appropriate dog food to feeding schedules.

A quality dog food has a proper balance of all the nutrients a dog requires together with a high level of palatability.

As a rule of thumb, each puppy in a litter should gain approximately its birth weight each week during the lactation or nursing period.

When a dog reaches full maturity, he enters the maintenance period. Normal healthy dogs who are not pregnant, nursing or hardworking have relatively low nutritional requirements for maintaining an appropriate body condition.

Aging dogs are defined as older or geriatric when they have reached the last 25 percent of their expected life span.
