What to Look For in Premium Medium Breed Sustainable Dry Puppy Food
The picks above are ranked by KibbleLab Score, our rubric-based read on a food's ingredients, nutrition, and AAFCO status. Here's what that rubric is actually checking for, so you can read any label yourself.
A named animal protein first
The first ingredient should name its animal source, like chicken, beef, or salmon, not a vague "meat" or an unnamed "animal by-product." It's the naming that matters: even a named by-product meal like "chicken by-product meal" is a real, nutrient-dense protein, while an unnamed one tells you nothing.
A complete AAFCO statement
Look for an AAFCO nutritional adequacy statement. It's what separates a food that's complete and balanced on its own from one only meant for supplemental feeding. For a puppy, it should meet AAFCO for growth, which is more demanding than an adult formula.
About the sustainability tag
These makers are accredited by the Pet Sustainability Coalition for their environmental and sourcing practices. That's a signal about the company, separate from whether a given food fits your pet, so still run the label checks.
Transparency you can check
Every premium medium breed sustainable dry puppy food here links to its full ingredient list, guaranteed analysis, and KibbleLab Score, so you can verify the label yourself instead of taking a brand's word for it.
Common Questions
How is this list of premium medium breed sustainable dry puppy foods ranked?
Ranked by KibbleLab Score, highest first. This page's filters decide which foods are eligible, then those foods are ordered by that score: our rubric-based read on a food's ingredients, guaranteed analysis, and AAFCO adequacy, built by an NAVC Certified Pet Nutrition Coach (PNCC). So the order reflects overall quality, not just the one trait this list is about. It refreshes weekly.
Do puppys really need a different food?
Yes. Puppys are growing fast and need more protein, fat, and specific minerals than adults, which is why a growth food should meet AAFCO for growth rather than adult maintenance.
Is a pricier food actually better?
Sometimes. A higher price can reflect named proteins, tighter sourcing, or more testing, but not always. Judge a food on its label and Score, not its price tag.
What should I look for on a dog food label?
A named animal protein as the first ingredient, a complete AAFCO statement for your dog's life stage, and a guaranteed analysis that fits their age and activity. Our Explains guides break down what each of those means.
How often does this list change?
It's rebuilt from KibbleLab's live catalog every week, so a food's score changing, a new food being added, or one going out of stock shows up within a week rather than instantly.
Why isn't my dog's food on this list?
A food appears here only if it matches this page's filters and scores high enough to place. Prescription diets are never listed. , or use Check a Food, to see how your own dog's food scores.
