Top dry dog food picks
Hill's Science Diet, Royal Canin (breed-specific lines), Purina Pro Plan (especially the Sport and Sensitive Skin formulas), and Blue Buffalo Life Protection are consistent bestsellers with reliable Repeat Delivery discounts.
Best wet dog food picks
Wellness CORE Pâté, Merrick Grain-Free, and Hill's Science Diet wet are commonly recommended for picky eaters and senior dogs needing softer texture.
Fresh & frozen
Petco carries Just Food For Dogs and similar fresh-cooked options either in-store or via subscription. Pricier per meal but increasingly popular for sensitive stomach and weight management.
Prescription diets
Hill's Prescription Diet and Royal Canin Veterinary Diet require a vet authorization and ship through Petco's prescription pet medication service.
How to stack the best deal
Combine: (1) Repeat Delivery for 5–35% off + free shipping, (2) any active brand promo, (3) Pals Rewards 5% back, (4) Vital Care members-only pricing where available. Stacked discounts can hit 30%+.
