Dur-A-Bulls Bone Treat
Verified Jun 20, 2026
This is a plant-based chew treat for dogs made primarily from brown rice flour and miscanthus grass, designed as a rawhide and plastic-free chewing option. With modest protein and fat levels, it functions as an occasional dental-style chew rather than a nutritional staple. It may suit dogs who enjoy long-lasting chews and whose owners prefer limited-ingredient, easily digestible alternatives to rawhide.
Nutritionally, this is a simple, limited-ingredient chew meant for occasional treating, not a source of complete nutrition. The main components are brown rice flour and miscanthus grass, which provide bulk and texture more than protein, so it works best alongside a balanced main diet. The single-treat calorie count is fairly high, so it’s most appropriate for dogs who are at a healthy weight and don’t get lots of other treats during the day.

At a Glance
KibbleLab Review
Strengths
- Limited-ingredient formula, which can be helpful for dogs that do better with simpler recipes.
- Made from digestible plant-based ingredients rather than rawhide or plastic, which many dogs tolerate well.
- Moderate fiber content from miscanthus grass may help support normal digestion in some dogs.
- Guaranteed analysis and calorie information per treat are provided, which makes it easier to factor into your dog’s daily calorie allowance.
Considerations
- At 558 calories per treat, this is a very calorie-dense chew, so portions and frequency need to be carefully limited, especially for small or overweight dogs.
- Low protein (6% minimum) and fat (3% minimum) mean this is not a significant source of nutrition and should only be used as an occasional treat alongside a complete and balanced diet.
- Contains cultured skim milk, so it may not be ideal for dogs with dairy sensitivities.
- As with any hard chew, there is some risk of dental fractures or gastrointestinal upset, particularly in aggressive chewers.

Top 5 Ingredients Explained
01
Brown Rice Flour
Brown rice flour is a gluten‑free carbohydrate source and functional binder commonly used in kibble, treats and some wet foods to provide digestible complex carbohydrates, a small amount of fiber, B‑vitamins and trace minerals while improving dough texture and extrusion properties. It supplies readily available energy for dogs (who tolerate grains well) but is not nutritionally essential for obligate‑carnivore cats; formulators should account for its caloric contribution, rare rice sensitivities, and the potential for low levels of inorganic arsenic, risks that are minimized by reputable sourcing and balanced diet formulation.
02
Glycerol
Glycerol (glycerin) is used in pet foods primarily as a humectant and sweetening agent to retain moisture, improve texture and palatability, and serve as a solvent or carrier in wet foods, treats, and liquid supplements. It provides a modest source of metabolizable energy for dogs and cats, but in large amounts can cause gastrointestinal upset and may affect blood glucose, so products intended for diabetic pets or sensitive animals should be used with caution.
03
Miscanthus Grass
Miscanthus grass is a processed perennial grass used in pet foods primarily as an insoluble dietary fiber and bulking agent to improve stool quality, support intestinal motility, and help reduce caloric density for weight management. It supplies little digestible protein or energy, tends to be more useful for dogs than obligate‑carnivore cats, and should be used in balanced formulations to avoid excessive fiber that could dilute nutrients or affect digestibility; sourcing and contaminant testing are also important considerations.
04
Natural Flavor
Natural flavor is used primarily as a palatability enhancer in pet foods to improve taste and aroma and is not intended to provide significant nutrients, typically coming from concentrated extracts of meat, poultry, plant, or fermentation sources. While it can increase acceptance in picky dogs and cats, manufacturers are not required to disclose specific sources so pets with known sensitivities or allergies may react, and presence of natural flavor should not be taken as a guarantee of overall product quality.
05
Natural Smoke Flavor
Natural smoke flavor is a concentrated flavoring used to give pet foods and treats a smoky aroma and improve palatability, but it provides virtually no protein, vitamins, or significant calories. It is generally added in small, regulated amounts and considered safe, though it can contain trace smoke‑derived compounds or added salts, so pets with respiratory sensitivities or strict sodium‑restricted diets should be monitored and owners may prefer products from manufacturers that test for contaminants.
