The scores
Open Farm: A (90/100) — Top-tier freeze-dried raw. Multiple named chicken proteins, organic vegetables, Certified Humane sourcing, no documented pathogen control.
Sundays: A (90/100) — Top-tier dehydrated. Four beef proteins, zero synthetic additives, 12 whole-food fruits and vegetables, no raw-handling needs.
Tied on rubric score but from different format classes — Open Farm earns the +6 freeze-dried-raw processing bonus but loses -3 for no documented HPP/test-and-hold; Sundays earns the +3 dehydrated processing bonus without the raw pathogen offset.
How the ingredients compare
Open Farm (Harvest Chicken Freeze-Dried Raw): Chicken with Ground Bone, Chicken Liver, Chicken Neck, Organic Butternut Squash, Organic Carrots, Organic Cranberries, Organic Blueberries, Coconut Oil, Dried Chicory Root, Organic Spinach, Organic Apple Cider Vinegar, Organic Kale, Salmon Oil, Dried Kelp, Organic Pumpkin Seeds, Organic Sunflower Seeds, Turmeric, Rosemary Extract
Sundays (Air-Dried Beef): Beef, Beef Heart, Beef Liver, Beef Bone, Quinoa, Pumpkin, Fish Oil, Sunflower Oil, Zucchini, Kale, Flaxseed, Dried Kelp, Dried Chicory Root, Turmeric, Mixed Tocopherols, Ginger, Selenium Yeast, plus 12 whole fruits and vegetables
Both formulas avoid every synthetic additive. Both front-load multiple named animal proteins (Open Farm with three chicken parts, Sundays with four beef parts). Both include a long whole-food tail of fruits, vegetables, and natural nutrient sources.
Where Open Farm pulls ahead
Freeze-dried raw processing: The highest processing bonus in our rubric (+6) reflects the superior preservation of heat-labile nutrients. Freeze-drying skips thermal processing entirely — food is frozen, then moisture sublimated in a vacuum at under 100°F. Heat-sensitive nutrients like taurine, certain B-vitamins, natural enzymes, and delicate omega-3s come through meaningfully more intact than in any cooked format.
Certified Humane and Global Animal Partnership sourcing: Open Farm publishes both Certified Humane and GAP certifications with a traceable supply chain documented on its website. Sundays describes USDA-inspected sourcing but without the same third-party certification stack.
Organic produce certifications: Open Farm’s vegetables and fruits are certified organic. Sundays’ are whole-food but not organic-certified. Shop on Amazon →
Where Sundays holds its own
No raw-handling safety caveats: Dehydration at 140–180°F eliminates the Salmonella/Listeria/E. coli risk profile that comes with any raw format. Sundays can be handled with normal bowl-cleaning hygiene; Open Farm requires the same precautions as raw chicken preparation. For households with infants, immunocompromised members, or anyone over 65, Sundays is the meaningfully safer choice. Open Farm is explicit about the raw safety caveat (we credit that transparency) but the caveat still applies.
Four-beef-protein stack depth: Sundays includes beef, beef heart, beef liver, and beef bone — four distinct beef parts in the top positions. Open Farm’s three chicken parts (meat with bone, liver, neck) is strong but narrower.
No pathogen-control transparency gap: Open Farm doesn’t publicly document HPP or test-and-hold pathogen testing for the freeze-dried line — under our rubric that’s a -3 deduction. Sundays doesn’t need pathogen control documentation because the format doesn’t carry that risk profile. Shop on Amazon →
The bottom line
Tied on rubric score, but the underlying choice is really about raw-vs-cooked preference and household safety tolerance. If you’re comfortable with raw handling, no household members in immunocompromised categories, and want the maximum nutrient preservation a commercial dog food can offer, Open Farm is the pick. If you want A-tier fresh-format nutrition with no raw safety caveats and full beef stacking, Sundays is the pick. Neither is wrong; the tradeoff is real and format-specific.
