Feeding Your Dog by Breed, Size and Life Stage

A complete and balanced food supplies every required nutrient, in the right proportions, for the stated species and life stage. In the United States, the AAFCO nutritional adequacy statement is where to find that. It names the food as complete and balanced for growth, adult maintenance, gestation and lactation, or all life stages.

Those are the four life stages AAFCO recognizes: growth, which includes puppies; maintenance, generally adult dogs; gestation and lactation; and all life stages. The statement also says how the food earned its claim. It was either formulated to meet the AAFCO Dog Food Nutrient Profiles, or it passed AAFCO feeding tests, or it is comparable to a food that did.

A food labeled for all life stages is built to meet the needs of the highest-demand stages, growth and reproduction. That makes it a fine choice for some households, though an adult or senior dog may do better on a food matched to adult maintenance. Treats, chews, mixers and foods marked for intermittent or supplemental feeding sit on top of a complete diet rather than replacing it.

Size shapes energy density, portion volume, growth speed and what overfeeding costs. Toy and small dogs have small stomachs and eat less volume, so they often need a relatively calorie-dense food, although age, activity, neuter status and body condition still move the number. Small dogs also tend to mature earlier than large ones. You can browse small dog breeds and large dog breeds to see where your dog fits.

Large and giant dogs grow for longer, and their puppyhood is the stage most sensitive to extra calories and mineral imbalance. A large-breed puppy needs a food made for large-size growth, with controlled calcium, phosphorus and energy density, and controlled feeding amounts. Fast growth raises orthopedic risk, and VCA advises against adding calcium supplements to a complete large-breed puppy diet unless a veterinarian prescribes them.

The timing of the switch from a growth diet to an adult one follows the individual dog, so your veterinarian can confirm when your puppy has finished growing.

Puppies need a diet formulated for growth, because their requirements for energy, protein and minerals differ from an adult's. Merck gives three meals a day from weaning to six months and two meals a day from six to twelve months as general starting points. Large and giant puppies also need calorie and mineral control, because rapid growth and extra weight load developing bones and joints.

Adult dogs need enough energy to hold body weight, muscle and condition. Needs shift after neutering, with less or more exercise, during pregnancy, with illness, or after a move. Checking weight and body condition every so often catches those shifts early.

Senior dogs have no single nutritional profile, and AAFCO has no senior adequacy statement. Aging can bring lower activity, muscle loss, weight gain, dental problems or chronic disease, as VCA describes. A senior formula suits some dogs, and the decision belongs after a veterinary assessment rather than at a birthday.

Extras work best as a small slice of the day. WSAVA and UC Davis both keep treats and non-complete foods to about 10% of daily calories or less, with a lower limit for some medical diets. Subtract them from the meal portion so the daily total stays steady.

Fresh water belongs in the bowl all day unless a veterinarian gives a medical reason to change that, according to Merck. Dogs that eat mostly dry food take in less water from the food itself, so they may drink more.

Raw and home-prepared diets are best discussed with your veterinarian or a veterinary nutritionist; the AVMA's policy on raw or undercooked animal-source protein is the place to read the cautions first.

These are the questions owners ask most, with short answers you can act on.

• What is the best nutritional diet for dogs?

  The best diet is a complete and balanced food for your dog's life stage and condition. The AAFCO statement, calorie information and sensible feeding directions are the tools for choosing. Body condition, activity, size, health and tolerance matter more than trendy ingredient claims.

• What are the 10 healthiest foods for dogs?

  No single list of ten foods suits every dog. Many healthy dogs can enjoy cooked egg, carrots, green beans, seedless apple, blueberries, strawberries, plain pumpkin, seedless watermelon, banana or a little plain cooked meat as extras, according to the AKC. Offer a small amount of any new food first and stop if digestive or allergic signs appear.

• Are eggs good for dogs?

  Plain, fully cooked eggs make an occasional treat for many dogs, adding protein and fat along with calories. Skip raw eggs, since raw animal products can carry pathogens, and serve eggs without salt, butter, onion, garlic or other seasonings. Dogs with pancreatitis, food allergies or other medical conditions need their veterinarian's advice first.

• What foods are no good for dogs?

  Chocolate, grapes and xylitol are among the recognized food hazards, so call a veterinarian, an emergency hospital or a poison-control service right away if your dog may have eaten one, and see DogServ for dog health and safety help.

• Is wet or dry food better for dogs?

  Either can be the better choice for a given dog, since both can be complete and balanced. Wet food holds more water and can be easier to eat; dry food is more concentrated by volume and easier to measure and store. Compare the adequacy statement, calories and life-stage match, and watch how your dog does. A mixed plan works when the combined portions add up to the intended daily calories.

• How do I choose a dog food without brand marketing?

  Ask the manufacturer who formulates the food, whether a qualified nutritionist is involved, how ingredients and finished foods are tested, where the food is made and whether nutrient analyses are available. WSAVA's guidance gives you these questions to put to any maker. Compare answers across a few foods with the label in hand.

• How much should I feed my dog?

  Begin with the calories and the label directions, then adjust for body condition, activity, age, neuter status, breed-related risk and health. Aim generally for a score of 4 to 5 on the 9-point chart, count treats, and recheck weight on a schedule. Your veterinarian can set a plan when weight changes without a clear reason.
