Royal Canin Size Health Nutrition Medium Puppy Dry Dog Food
The most sharply targeted puppy food here - breed size, growth window and kibble geometry are all specified. The ingredient panel starts with chicken by-product meal, so it wins on precision rather than on ingredient prestige.
Score breakdown

Weight 30% · Algorithm-computed score 38/100

Weight 20% · Algorithm-computed score 52/100

AAFCO statement: Formulated to meet the nutritional levels established by the AAFCO Dog Food Nutrient Profiles for growth, including growth of large-size dogs (70 lb or more as an adult).. Formulated-to-meet profiles are acceptable but weaker evidence than feeding trials, which caps the score here.
Weight 14% · Editorially assessed score 88/100
Four recalls: a 2006 vitamin D3 excess that the company self-detected and veterinarians widely praised as a textbook response, two 2007 melamine-era withdrawals, and a January 2023 mislabelling advisory on a single lot of a veterinary renal diet. No retail dog or cat food has been recalled since 2007.
Weight 10% · Algorithm-computed score 92/100
Algorithm: about $2.09 per 1,000 kcal ($$ tier), normalized against same-species peers, wet and dry together (cheapest = 100, most expensive ≈ 15).

Owner ratings are consistently high across major retailers, with few recurring palatability complaints.
Pros and cons
What we like
- Built for a specific window: medium-breed puppies from 2 to 12 months expected to finish at 23-55 lb
- 30% protein and 18.4% fat with added DHA from marine microalgae oil - among the highest fat levels in this ranking
- Kibble size and shape are engineered for medium-breed jaws, which genuinely affects how much puppies eat
- Royal Canin has not recalled a retail dog food since 2007
What we don't
- Chicken by-product meal leads, ahead of any named whole meat
- About $3.67/lb from the 30 lb bag and roughly $2.09 per 1,000 kcal - expensive for a puppy food you replace quickly
- Corn and wheat both appear in the top five
Ingredients & nutrition analysis
The first five ingredients tell most of the story:
Royal Canin's whole proposition is precision rather than ingredient romance, and this bag is the clearest example: it is formulated for puppies whose adult weight will land between 23 and 55 lb, for the short high-energy growth window up to 12 months, with a kibble shape designed for medium jaws. The 18.4% fat and added DHA reflect that energy density.
You pay for it. At $3.67/lb from the 30 lb bag - about $2.09 per 1,000 kcal - this is one of the pricier puppy foods here, and chicken by-product meal, corn and wheat occupy the top five. The counter-argument is Royal Canin's record: no retail dog food recall since 2007, and a 2006 vitamin D3 problem the company caught itself.
