Most puppies do best on 3–4 meals a day early on, switching to two meals a day around 4–6 months as they grow. Exact timing varies by breed and size, so your vet is the best resource for a feeding schedule tailored to your puppy specifically. Learn more about how much to feed your puppy.

Growing puppies have higher protein needs than adult dogs, since protein fuels muscle, tissue, and immune development during rapid growth. Look for puppy food with real animal protein first, ideally at or above the minimum AAFCO requirement for growth, 22.5% crude protein on a dry matter basis.

The biggest difference between puppy food and adult dog food is growth needs. Puppy food is more calorie- and protein-dense, with DHA for brain and eye development, while adult formulas focus on maintaining energy, muscle, and overall health long-term.

DHA is an omega-3 fatty acid critical for brain and eye development in growing puppies. High-quality puppy food includes DHA-rich ingredients like fish oil to support cognitive function and vision during the fastest-growing months of a puppy's life.

Most puppies can switch from puppy food to adult food around 12 months old, though large breeds often stay on puppy food longer — up to 18–24 months — to support slower, controlled bone and joint growth. Your vet can confirm the right timing for your puppy's breed and size.
