Iams vs The Farmer's Dog

Iams (mass-market-priced kibble from a maker that meets 4 of WSAVA's 5 questions, for budget-conscious owners) 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. Both brands meet 4 of 5 WSAVA criteria. Iams is roughly 83% less than The Farmer's Dog.

The verdict

This is the widest price gap in the lineup. Iams meets 4 of 5 WSAVA criteria, with a "formulated to meet" AAFCO label rather than feeding trials, at a mass-market $25-45/month; The Farmer's Dog is a fresh-cooked subscription meeting 4 of 5, with on-staff board-certified veterinary nutritionists and an AAFCO feeding-trial affidavit for its Chicken Recipe, but cooked in partner kitchens, at $150-250. Up to roughly six times the cost.

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 Iams for a tight budget and travel-friendly shelf stability. Pick The Farmer's Dog only if you have the budget, a picky dog, or mild transitional GI issues, and don't board or travel often.
