Quick Verdict

Both of these treats represent the gold standard of ingredient transparency: single-ingredient, freeze-dried, nothing hidden. The difference comes down to what that one ingredient is and what you pay for it. Stewart gives you 14 ounces of beef liver for $36, while Stella & Chewy's gives you 3.25 ounces of grass-fed beef for $15. If your primary concern is delivering the cleanest possible treat at the best value, Stewart wins. If grass-fed sourcing and ethical provenance matter to you, Stella & Chewy's justifies its premium.

Head-to-Head Comparison

Ingredient Quality

Winner: Stella & Chewy's (narrowly)

Both treats contain exactly one ingredient with zero fillers, preservatives, or additives. You cannot get cleaner than a single-ingredient treat. The distinction comes down to the source material itself.

Stella & Chewy's uses 100% grass-fed beef — the muscle meat, not organ meat. Grass-fed beef generally offers a better omega-3 to omega-6 fatty acid ratio and is free from the hormones and antibiotics commonly used in conventional cattle farming. The company emphasizes responsibly sourced, cage-free, grass-fed supply chains.

Stewart uses 100% beef liver, which is nutritionally dense — packed with iron, vitamin A, vitamin B12, and copper. Liver is arguably more nutrient-rich per ounce than muscle meat, though the sourcing transparency is less detailed. Stewart does not specify grass-fed or conventional sourcing.

For pure nutritional density, liver has an edge. For sourcing ethics and provenance, Stella & Chewy's is clearly ahead.

Calorie & Nutritional Profile

Winner: Stewart (for treat use)

Beef liver is inherently lower in fat and calories than muscle meat, making it slightly better suited for frequent treat use without weight management concerns. The dense micronutrient profile — iron, B vitamins, vitamin A — means your dog gets genuine nutritional value from what is essentially a reward.

Stella & Chewy's grass-fed beef delivers quality protein with a favorable fatty acid profile, but the higher fat content of muscle meat means slightly more calories per ounce. For training-heavy use where you might go through dozens of pieces in a session, liver's lower calorie density is a practical advantage.

That said, both are dramatically better than processed treats loaded with starches and fillers. You are comparing good to slightly better.

Ingredient Transparency

Winner: Tie (perfect)

Both earn perfect transparency scores, and they should — there is literally one ingredient in each product. No vague terms, no unnamed protein sources, no processing aids buried in the fine print. What you see is what you get.

Stewart's simplicity is its transparency: beef liver. Full stop. Stella & Chewy's adds sourcing context on top of the simplicity: grass-fed, cage-free, responsibly sourced beef. Both approaches are admirable, with Stella & Chewy's providing more detail about the supply chain upstream.

Palatability & Acceptance

Winner: Stewart

This is where Stewart pulls ahead decisively for most dogs. Liver has an aroma and flavor intensity that most dogs find absolutely irresistible. The strong smell that some owners find off-putting is exactly what makes liver a high-value training reward. Professional trainers have used liver treats for decades precisely because dogs will work harder for liver than for almost anything else.

Stella & Chewy's beef treats are also highly palatable, but muscle meat simply does not trigger the same intensity of response in most dogs. Both are significantly more appealing than processed treats, but liver is the superior motivator.

Value Per Treat

Winner: Stewart (decisively)

The math here is stark. Stewart gives you 14 ounces for $36.09, which works out to roughly $2.58 per ounce. Stella & Chewy's gives you 3.25 ounces for $14.99, which is $4.61 per ounce. Per ounce, Stella & Chewy's costs nearly 80% more.

Stewart also offers larger package sizes, meaning less frequent repurchasing. For anyone going through treats regularly — training, daily rewards, puzzle toys — the cost difference compounds quickly. Over a year of moderate use, you could spend $100+ more on Stella & Chewy's for the same volume of treats.

Safety Record

Winner: Tie

Neither brand has significant recall history. Stewart has been manufacturing freeze-dried treats for over 50 years, giving them one of the longest track records in the industry. Stella & Chewy's has built a strong reputation since 2003 with rigorous quality control in their freeze-dried product line. Both are safe choices.

When to Choose Stella & Chewy's Carnivore Crunch

Stella & Chewy's is the right choice when:

• Grass-fed sourcing matters to you: You specifically want treats from responsibly raised, grass-fed cattle
• You prefer muscle meat over organ meat: Some owners are uncomfortable feeding organ meat, even though it is nutritionally excellent
• Your dog has liver sensitivity: Some dogs can experience digestive upset from rich organ meat — muscle meat is gentler
• You use treats sparingly: The smaller bag size and higher price are less impactful if you use only a few treats per day
• Brand philosophy resonates: Stella & Chewy's raw-feeding ethos and supply chain story appeal to you

When to Choose Stewart Freeze Dried Beef Liver

Stewart is the right choice when:

• Value matters: Nearly twice the product per dollar with comparable ingredient quality
• You train frequently: High-volume treat use makes the per-ounce price difference significant
• Maximum palatability is the goal: Liver is the stronger motivator for most dogs
• Nutrient density appeals to you: Liver delivers more micronutrients per ounce than muscle meat
• You need a high-value reward: For challenging training scenarios where you need your dog's full attention

Final Recommendation

For most dog owners, Stewart Freeze Dried Beef Liver is the better value. You get a single-ingredient, freeze-dried treat with exceptional palatability, strong nutritional density, and a per-ounce cost that makes daily use sustainable. The 50-year manufacturing track record provides confidence in safety and consistency.

Choose Stella & Chewy's if sourcing provenance is your priority. The grass-fed, responsibly sourced beef and the brand's transparent supply chain justify the premium for owners who align with that philosophy. It is a genuinely excellent treat — just significantly more expensive per ounce.

Both are single-ingredient, freeze-dried, and free from anything you would not want your dog eating. The difference is provenance, price, and protein type — and for everyday use, Stewart's liver delivers more for less.
