Puppy food and senior dog food: feeding your dog at every age

Puppies and older dogs need different things from their food. Here is what changes, and when.

Puppies

Choose a food made for growth

Puppies need more calories, protein and certain minerals than adult dogs. Look for a statement that the food is complete and balanced for growth, or for all life stages. If your puppy will weigh 32 kg (70 lb) or more as an adult, the label should also say it covers the growth of large-size dogs. Large-breed puppies need carefully controlled calcium so their bones grow at the right pace. Fromm Gold Puppy, for example, is formulated for growth including large breeds.

Don't add calcium or other supplements to a complete puppy food unless your vet tells you to.

How often to feed

AgeMeals a day
8 to 12 weeks4
3 to 6 months3
6 months and older2

Follow the feeding guide on the bag and weigh your puppy every week or two. Keep treats under about 10 percent of the day's food, which matters even more while a puppy is growing.

When to switch to adult food

Adult sizeSwitch at about
Small (under 10 kg / 22 lb)9 to 12 months
Medium (10 to 25 kg / 22 to 55 lb)12 months
Large (25 to 45 kg / 55 to 100 lb)12 to 18 months
Giant (over 45 kg / 100 lb)18 to 24 months

Your vet can tell you when your puppy has finished growing. Change foods over 7 to 10 days; our raw diet guide has a day-by-day switching table that works for any food.

Senior dogs

Dogs are usually considered seniors from about 7 years old. Large breeds age sooner and small breeds later.

What changes

  • Calories: many older dogs are less active and gain weight easily. Weigh your dog monthly and adjust portions; a lean dog moves more easily.
  • Protein: healthy senior dogs still need good-quality protein to keep their muscle. Don't cut protein unless your vet advises it, for example for kidney disease.
  • Joints: some senior foods add glucosamine, chondroitin or fish oil. Our fish oil guide explains how to add it.
  • Teeth: sore teeth make kibble hard to eat. Adding warm water, a softer food or a wet topper helps, and so does a dental check.
  • Appetite: if your senior dog turns picky, warm the food slightly or try a topper. A sudden change in appetite, thirst or weight needs a vet visit.

There is no official nutrient standard for senior food, so recipes vary a lot between brands. Compare calories and protein on the label instead of choosing on the word "senior" alone. Most vets suggest a checkup every six months for senior dogs.
