Dog food is the single largest ongoing expense of dog ownership — you'll spend more on food over your dog's lifetime than on vet bills, grooming, or boarding. The monthly cost depends on your dog's size, the food quality (kibble vs. fresh vs. raw), and whether you need prescription food for a health condition.
The average cost of dog food is $20 to $90 per month for standard kibble, $60 to $150 per month for fresh food delivery, and $80 to $250+ per month for raw or prescription diets.

Frequently Asked Questions
How much does dog food cost per month?
Dog food costs $20 to $90 per month for kibble, $60 to $150 for fresh food delivery, and $80 to $250 for raw or prescription diets. A medium dog (25–50 lbs) costs $25–$50/month on kibble. Small dogs (under 25 lbs) cost $15–$30/month. Giant breeds (80+ lbs) cost $50–$90/month on kibble or $120–$250 on fresh food.
How much does dog food cost per year?
Dog food costs $240 to $1,080 per year for kibble, $720 to $1,800 for fresh food, and $960 to $3,000 for prescription food. Over a 10-year lifespan, you'll spend $2,400–$10,800 on kibble or $7,200–$18,000 on fresh food. Food is the largest lifetime expense of dog ownership — more than vet bills, grooming, or boarding.
Is expensive dog food worth it?
Higher-quality food can reduce vet costs long-term by preventing allergies, digestive issues, and obesity. Premium kibble ($35–$60/month) is the sweet spot — better ingredients than basic kibble without the premium price of fresh or raw. Fresh food ($60–$150/month) is worth it for dogs with allergies, sensitive stomachs, or picky eating. Prescription food ($80–$250/month) is necessary for medical conditions and not optional.
What's the cheapest way to feed my dog?
The cheapest options are: basic kibble ($20–$35/month), DIY raw diet with bulk meat ($50–$80/month), and homemade food with rice, chicken, and vegetables ($40–$80/month). Buying in bulk, using autoship discounts (Chewy offers 5–10% off), and choosing larger bag sizes reduces per-meal cost. Avoid overfeeding — measure portions to prevent waste and obesity.
