Curly Beef Collagen Stick Treat
Verified Aug 24, 2026
A high-protein beef collagen chew designed as a long-lasting treat for dogs of all sizes. It uses beefhide-derived collagen with a bit of added beef and vegetable glycerin to create a firm, curly texture that encourages chewing. This is a supplemental chew for enjoyment and oral exercise, not a complete diet or meal replacement.

Top Pick
This is a simple, single-animal–source collagen chew that can work well as an occasional high-protein treat for most healthy dogs. The ingredient list is short and straightforward, and the curly shape encourages chewing, which can help mechanically clean teeth. Because it’s quite calorie-dense per stick and not a balanced food, it should be given in moderation and not used as a primary source of nutrition.

Strengths
- Very limited ingredient list, with collagen from beefhide and beef as the main components, which can be helpful for owners wanting to avoid mixed or unclear protein sources.
- High protein content (75% minimum on an as-fed basis) consistent with a true animal-derived chew rather than a filler-based treat.
- Firm, curly texture encourages chewing, which can help reduce soft plaque buildup on teeth through mechanical abrasion.
- Clear calorie information per treat (about 150 kcal) helps owners factor this into their dog’s daily intake.
Considerations
- Not a complete or balanced diet and should only be used as an occasional chew; regular dog food is still needed to meet all nutrient requirements.
- Each stick is relatively high in calories (around 150 kcal), so portions need to be limited, especially for small or less active dogs to avoid unwanted weight gain.
- Contains beef, which is a common food allergen for some dogs; it isn’t appropriate for dogs with known beef allergies or sensitivities.
- As with any firm chew, there is some risk of gastrointestinal upset, choking, or blockage, especially if dogs swallow large pieces or are aggressive chewers, so close supervision is important.

Top 5 Ingredients Explained
01
Collagen
Collagen is an animal-derived structural protein commonly added to pet foods and supplements as gelatin or hydrolyzed collagen to support joint, skin and coat health and to provide digestible connective-tissue protein for dogs and cats. It supplies key amino acids such as glycine and proline important for cartilage and skin maintenance but is low in tryptophan and not a complete protein—so it should not replace higher-quality muscle proteins—and pet owners should note source quality and potential allergen/contaminant concerns.
02
Beef
Beef is commonly used in dog and cat foods as a primary animal protein and palatability enhancer, supplying high-quality essential amino acids, B vitamins, iron, and zinc that support muscle maintenance and overall health. Owners should note beef can be calorie- and fat-dense and is a relatively common allergen, and raw or improperly handled beef carries microbial risks, so formulation, fat content, and sourcing/processing are important considerations.

03
Vegetable Glycerin
Vegetable glycerin is a plant-derived humectant and sweet-tasting solvent commonly used in pet foods and treats to retain moisture, improve texture, dissolve flavorings or vitamins, and enhance palatability. It provides usable calories, is generally regarded as safe for dogs and cats in typical amounts, but excessive intake can cause digestive upset and may be a consideration for diabetic pets or those needing calorie-restricted diets.
