6 Smart Ways to Reduce Dog Food Costs

Measure portions accurately — Most owners overfeed by 20-30%. Use a kitchen scale, not a scoop.
Buy larger bags — 30-40lb bags save 28-44% vs 15lb bags.
Use Subscribe & Save — Chewy and Amazon offer 5-10% off recurring orders.
Choose mid-tier brands — Purina Pro Plan or Iams offer 90% of the quality at 50-70% of the price of premium brands.
Time your purchases — Black Friday, Cyber Monday, and January sales offer 25-40% off.
Limit treats — Treats add $10-30/month and extra calories. Use kibble for training instead.
