Quick answer
For most Australian Shepherd puppies our editorial team leans toward Purina Pro Plan Puppy Chicken and Rice Formula as the best overall pick, because it leads with a named meat, carries an AAFCO statement for growth, and delivers the protein, fat, and calories an active medium breed pup typically needs. If your Aussie has a sensitive stomach, Hill’s Science Diet Puppy is a gentler option, while Diamond Naturals Puppy is the budget pick that still covers the basics. Choose Royal Canin Medium Puppy if you want kibble shaped and timed for medium breed growth, and Wellness Complete Health Puppy if you prefer a grain inclusive recipe with omega support.
What to consider for Puppy Food For Australian Shepherd
Australian Shepherds are a herding breed bred for stamina, so puppies tend to be busy, mentally sharp, and quick to burn calories. They usually mature into the medium size range, roughly 40 to 65 pounds, which means most do well on a standard puppy or medium breed puppy formula rather than a large breed specific food. That said, an Aussie near the top of that weight range benefits from controlled calcium and a moderate calorie density so growth stays steady rather than rushed.
This breed is also prone to weight gain when activity drops, and an overweight puppy puts extra load on developing joints, so portion control matters as much as the food you pick. Aussies can be sensitive to abrupt changes, so transitions should be gradual. Because the breed has a higher reported rate of certain inherited eye and hip conditions, talk to your veterinarian about screening and never rely on food alone to manage a medical concern. Food supports healthy development, it does not replace veterinary care.
What to look for in a dog food
Start with the label. Look for an AAFCO statement of nutritional adequacy for growth, or for “all life stages,” so you know the food is formulated as a complete diet for a puppy and not just a topper or supplement. A named meat as the first ingredient, such as chicken, lamb, or salmon, is a good sign of where the protein comes from, rather than a vague “meat meal” alone.
For an active medium breed puppy, many growth foods land around 26 to 32 percent protein and 14 to 20 percent fat on a dry matter basis, with calorie density often near 350 to 450 calories per cup. Treat these as practical ranges, not strict medical rules, and let your veterinarian guide adjustments. Calcium for growth is usually best in a controlled range, which matters more as your Aussie approaches the larger end of medium. Omega 3 fatty acids like DHA support brain and eye development in puppies, and ingredients such as fish oil or named fish can help. Large breed labeling is generally not required for a typical Aussie, but small breed kibble may simply be easier for smaller pups to chew.
How we chose these picks
- Confirmed each product is currently sold and widely available from major retailers including Amazon.
- Required an AAFCO statement of nutritional adequacy for growth or all life stages on the label.
- Prioritized recipes that list a named meat as the first ingredient rather than an unnamed meal alone.
- Checked that protein, fat, and calorie levels fit an active medium breed puppy in practical ranges.
- Favored brands with established quality control, feeding-data review history, or nutritionist involvement.
- Reviewed publicly reported recall history and manufacturer transparency before including any food.
- Compared owner feedback for digestibility and palatability, noting common complaints honestly.
- Never ranked a product higher just because it pays a commission.
What to avoid
- Foods that list only an unnamed “meat meal” as the protein source, with no named animal, since you cannot tell what you are feeding.
- Defaulting to grain-free or legume-heavy recipes without a reason. The FDA investigation into a potential link between certain diets and canine dilated cardiomyopathy is ongoing, and grain inclusive is the safer default unless your veterinarian advises otherwise.
- Feeding an all life stages or adult food to a puppy that may finish on the larger end, since uncontrolled calcium and calories can push growth too fast. Match the life stage to your pup.
- Abrupt diet switches. Aussies can react with loose stools, so transition over 7 to 10 days by gradually mixing new food into the old.
