Hill's Science Diet vs The Farmer's Dog

Hill's Science Diet (veterinarian-recommended premium kibble with the deepest prescription-diet portfolio on the market) and The Farmer's Dog (fresh-cooked subscription with the largest market share; meets 4 of WSAVA's 5 questions, with a feeding-trial affidavit but partner-kitchen production) compared head-to-head on WSAVA manufacturer-quality criteria, AAFCO substantiation, monthly cost, and which dog each is best for in 2026. Hill's Science Diet meets 5 of 5 WSAVA criteria. Hill's Science Diet is roughly 65% less than The Farmer's Dog.

The verdict

This is the classic kibble-versus-fresh decision. Hill's Science Diet is a fully WSAVA-compliant premium kibble meeting all 5 criteria with AAFCO feeding trials at $55-85/month; The Farmer's Dog is a fresh-cooked subscription that meets 4 of 5, employs board-certified veterinary nutritionists, and backs its Chicken Recipe with an AAFCO feeding-trial affidavit, but cooks in partner kitchens and costs $150-250.

The Farmer's Dog brings higher digestibility in published studies and strong palatability for finicky eaters, at 2-6x kibble's per-calorie cost with cold-chain shipping. Pick Hill's for clinical track record, owned plants, prescription continuity, and travel-friendly shelf stability. Pick The Farmer's Dog if you have the budget, a picky dog, or mild transitional GI issues, and don't board or travel often.
