| Understanding the role that protein plays throughout a dog's life
is important because puppies and geriatric dogs need extra protein compared to
the healthy adult dog. Research suggests that healthy geriatric dogs may need
higher levels of protein than healthy adult dogs. Recently, Purina Pet
Products reformulated its senior dog foods to have higher protein. "There is a
myth that older dogs do not need high levels of protein. Research indicates that
the exact opposite is true: older dogs may actually need more protein than younger
dogs. If an elderly dog is healthy, higher levels of protein will help maintain
lean body mass and support immune functions," says Dottie Laflamme, DVM, PhD,
of Ralston Purina Company. Geriatric Dogs Need High Levels
of Protein
Research conducted at the Purina Pet Care Center as well
as other institutions indicates that healthy geriatric dogs digest protein in
a similar manner to young adult dogs. However, they may be less efficient in metabolizing
protein after absorption. In order to maintain optimum protein reserves healthy
geriatric dogs may need more protein than younger adult dogs. "Higher protein
does not necessarily mean higher calories. It is important to be sure that the
protein/calorie ratio is properly adjusted to meet the specific energy needs of
the aging dog," says Laflamme. Less active older dogs often have reduced
energy requirements and may benefit from a lower calorie dog food with an adjusted
protein/calorie ratio, such as Purina® Senior, Pro Plan® brand Reduced Calorie
or Purina O.N.E.® brand Reduced Calorie dog foods. Protein
Intake Helps Females During Pregnancy
Although protein is important
to other canines, it is crucial during reproduction, especially before puppies
are born. Pregnant bitches need to receive proper nutrition during the pregnancy.
Inadequate nutrition during this critical period can affect the puppies even months
later. During the last trimester when fetuses are growing rapidly, they
depend heavily upon the female's diet for essential nutrients. During these last
two to three weeks, expecting bitches should be fed a diet containing more than
1600 metabolizable calories per pound of food and at least 21 percent protein.
The protein, along with the other nutrients, helps the fetuses grow and develop
properly. As always, when a complete and balanced food for all life stages is
fed, supplements are not necessary. While food intake normally fluctuates, it
is important to remember that overweight bitches can have lower conception rates
and more problems at whelping. Protein Is Important
to the Growth of Puppies
Puppies' diets require special attention.
Feeding puppies the correct amounts of nutrients helps ensure proper growth. Puppies
should begin nibbling solid food by three to four weeks of age. At week six, puppies
are usually ready to be weaned. To ensure normal growth and development puppies
need about twice the nutrition per pound of body weight than they will as adult
dogs. This can best be accomplished by feeding a nutritionally dense food. Puppy
foods such as Purina® Puppy Chow® brand dog food or Purina O.N.E.® brand puppy
formula are specially formulated to meet the special nutritional needs of puppies.
They do this by offering higher levels of protein, iron and other nutrients in
a highly digestible form. Hardworking Dogs Need More
Protein
Compared to less active pets, hardworking dogs require higher
levels of protein, calories and fat in their diet to maintain stamina and good
body condition. Choose a dry dog food that is complete and balanced and includes
at least 26 percent protein and 1650 kilocalories of metabolizable energy per
pound. During the seasons when dogs are not working, their energy requirements
decrease. Feed less of the high calorie food or gradually change to a less nutrient-dense
dog food. Maintaining dogs in good body condition in the off season will help
make conditioning less stressful. Protein is important at all life stages,
and it should always be present in dogs' diets. Fetuses to puppies to geriatric
dogs all need protein because it enables their bodies to grow, reproduce and stay
healthy. If you show, breed, board, trial or feed five or more dogs, call 1-800-851-3148
