How to Feed a Large-Breed Puppy for Healthy Growth

By Tailwisp Editorial TeamUpdated October 17, 20263 min read

Large and giant breed puppies are growing at an astonishing rate. A Great Dane may go from about half a kilogram at birth to more than fifty kilograms in a year. That growth puts stress on developing bones and joints, so feeding matters a great deal.

Why growth rate matters

Bones and joints need time to develop properly. Overfeeding, which causes rapid weight gain, and unbalanced minerals have been linked with developmental orthopedic diseases such as hip and elbow dysplasia, osteochondrosis and growth abnormalities. Genetics also play a major part, but diet is one factor you can control. See our guide to hip dysplasia in dogs.

Choose a large-breed puppy food

Look for a food that:

• States it is formulated for large or giant breed puppies
• Carries a complete and balanced statement for growth. See AAFCO and FEDIAF standards
• Has controlled calcium and phosphorus levels
• Has moderate energy density
• Comes from a manufacturer with veterinary nutritionists and good testing

Avoid adult foods and foods made for all life stages unless they are specifically labeled as suitable for large breed growth.

Do not supplement calcium

Large-breed puppy foods already contain carefully balanced calcium. Adding calcium supplements, dairy or bones can upset the balance and increase the risk of bone problems. See our guide to essential minerals. Ask your vet before adding any supplement.

Meal frequency

Feed three meals a day until about six months, then reduce to two. Measured meals help control growth and reduce bloat risk compared with free feeding. See our guide to puppy feeding by breed size.

Keep your puppy lean

A lean puppy is a healthier puppy. You should be able to feel the ribs easily and see a waist. Check body condition regularly using our body condition score chart. If your puppy is getting heavy, reduce the portions, not the quality.

Monitor growth

Weigh your puppy every two weeks and record the results. Your vet can compare the curve with expected patterns. Steady growth is better than a steep curve. See our puppy growth chart guide.

Exercise considerations

Avoid forced or high-impact exercise such as long runs or jumping while joints are developing. See our guide to puppy exercise limits by age. Slippery floors can also strain joints, so provide traction.

Bloat risk

Large, deep-chested breeds are at risk of bloat. Feed measured meals, avoid vigorous exercise around mealtimes and discuss prevention with your vet. See our guide to bloat in dogs.

Treats and chews

Count treats in daily calories, and choose low-calorie options. See healthy dog treats.

When to switch to adult food

Large breeds mature slowly, so many stay on large-breed puppy food until twelve to eighteen months, and giant breeds longer. Your vet will advise. Switch gradually. See how to switch dog food safely.

Signs of trouble

Contact your vet if you notice limping, swollen joints, bunny-hopping, reluctance to exercise or sudden changes in growth.

Spay and neuter timing

Timing may affect joint health in some large breeds. Discuss it with your vet.

Buying and storing the right food

Check the bag for the words "large breed puppy" and for the adequacy statement. Buy a size you can finish within a few weeks, because fats go stale, and keep the food sealed in a cool place. If you ever need to change brands, do it slowly over about a week, and keep the same type of food, large-breed puppy to large-breed puppy, so the calcium level stays controlled.

The takeaway

Feed a large-breed puppy for steady growth: the right food, measured meals, lean body condition and no extra calcium. The effort pays off in a healthier adult.
