At $31.38 for 16oz (approximately 360 pieces), Stewart works out to about $0.087 per treat — under 9 cents. For a dog owner doing daily training sessions, this is one of the most cost-effective high-value treat options available. Comparable single-ingredient freeze-dried liver from premium brands runs 2–3× more per treat.

Cost per treat breakdown
| Product | Size | Price (approx.) | Approx. pieces | Cost per piece |
|---|---|---|---|---|
| Stewart Beef Liver | 16 oz | $31.38 | ~360 | $0.09 |
| Vital Essentials Beef Liver | 2.1 oz | $9.99 | ~70 | $0.14 |
| Primal Beef Liver | 2 oz | $7.49 | ~60 | $0.12 |

| Ziwi Peak Treats | 3.5 oz | $12.99 | ~90 | $0.14 |
Stewart is the cheapest per piece among comparable single-ingredient freeze-dried liver treats. The 16oz bag size is a significant factor — most competitors sell primarily in 2–4oz bags, where the per-ounce price is higher.
Cost per training session comparison
A typical 15-minute positive reinforcement training session might use 30–50 reward events. Using broken pieces (each standard piece broken into 4–5 bits), that is 7–12 whole pieces per session. At $0.09 per piece, a 15-minute training session costs approximately $0.63–$1.08 in Stewart liver treats.
Using a comparable Vital Essentials bag at $0.14 per piece, the same session costs $0.98–$1.68. For an owner training every day, that is $13.50–$23.00/month for Stewart versus $21–$37/month for Vital Essentials. The difference — roughly $7–14 per month — may or may not matter to you, but it is real.
Monthly cost estimate by use level
| Use level | Pieces/day | Stewart cost/month | Comparable premium cost/month |
|---|---|---|---|
| Light (occasional rewards) | 5–10 | ~$4.00 | ~$6–8 |
| Moderate (daily short sessions) | 20–30 | ~$8.10 | ~$12–15 |
| Heavy (intensive daily training) | 50–80 | ~$16.50 | ~$25–35 |
Cheaper alternatives and what they cost in quality
Home-dehydrated beef liver is the cheapest option: raw beef liver from a grocery store or butcher costs $2–4/pound, and a food dehydrator will process it for roughly the same single-ingredient result. The tradeoff is time (preparation, cleaning, 6–8 hours dehydrating) and moisture content (home dehydrating typically leaves more moisture than commercial freeze-drying, shortening shelf life to 2–3 weeks for dehydrated vs 12+ months for freeze-dried).
Generic or store-brand freeze-dried treats are another option. Quality varies significantly — the single-ingredient claim does not mean equivalent processing. Stewart's 50-year track record and USDA certification is a meaningful quality signal that generic alternatives may not provide.
When the premium is worth it
The simple answer: if these treats are your primary training tool and your dog's high-value reward, the quality and palatability consistency is worth paying for vs. cheaper alternatives. The 16oz bag size means you get a lower per-ounce price than most competitors while still getting a premium product. Stewart hits a useful price-quality intersection that is hard to match in the freeze-dried liver category.
