Woofley's 6 Inch Collagen Sticks for Dogs - (100 Count) Bull

The Verdict

Let’s be direct about what these are: 100 collagen sticks, roughly the size and shape of a classic bully stick, but made from beef collagen rather than pizzle. If your dog is a serial chewer and you’re bleeding money on single-serve treats, the bulk math here is the first thing that grabs you.

What You Actually Get

Open the bag and you’re looking at a solid mass of tan, rawhide-adjacent sticks. They’re 6 inches long, roughly pencil-thick at the narrow end and closer to a sharpie at the wide end — though I’ll flag the size consistency issue in a moment. No artificial colors, no preservatives listed on the packaging, just a single-ingredient collagen chew. The smell is present but mild; it’s closer to a faint bone broth aroma than the eye-watering funk of traditional bully sticks. That’s a genuine win for anyone who’s ever had to hide the chew bag from houseguests.

Real-World Performance

I tested these with a 45-pound lab mix who’s a dedicated medium-duty chewer. A single stick lasted around 35 minutes of active gnawing — not as long as a high-density bully stick, but significantly longer than a pressed rawhide roll. The collagen softens as they work it, which is good for dental health (the abrasive texture does scrape off mild plaque) and bad for the impatient dog who decides to swallow chunks whole.

Here’s the honest concern: these are not indestructible. They’re firmer than rawhide, but a determined power chewer — think German Shepherds, pits, or any dog who’s destroyed a “tough” toy in under ten minutes — can break these into pieces. If that’s your dog, you need to supervise every session. Multiple reviewers note this exact issue. One buyer wrote, “My golden retriever loves them, but my neighbor’s rottweiler went through one in about 12 minutes and I pulled a chunk out of his throat.” That’s the reality check. Moderate chewers, small-to-medium breeds, and puppies teething? These are excellent. Heavy chewers? Buy one bag, test one stick, watch closely.

The Consistency Problem

Now the downside that keeps this from a 4.5+ rating. The 6-inch length is generally accurate, but thickness varies. I pulled out sticks that were noticeably thinner than others — probably 20% of the bag was on the slender side. That matters because thinner sticks break down faster and pose a slightly higher choking risk. It’s not a dealbreaker, but it means you can’t assume “one size fits all” for your dog’s chewing style. Also, the bag itself is a simple clear plastic pouch with no zipper. With 100 sticks, you’ll want to transfer these to a sealed container or they’ll dry out and get brittle.

Who Should Buy These

This is the sweet spot: owners of small-to-medium dogs, moderate chewers, and puppies who need something to gnaw on during teething. If you’ve got a dog who goes through one chew per day, the 100-count bag becomes a two-to-three-month supply for roughly the price of a dozen premium bully sticks. That’s the value proposition, and it’s a strong one.

Skip these if you have a heavy power chewer, a dog with a history of swallowing large pieces, or if you need guaranteed size consistency for training treats.

FAQ

Are these digestible? Collagen is a protein, so yes, it breaks down in the stomach more easily than rawhide. But that doesn’t mean it’s safe to inhale. If your dog gulps whole chunks, cut the sticks into smaller sections.

Will these stain my carpet? Less than traditional bully sticks, but they still leave a wet spot if your dog chews on fabric. Give them a towel or chew mat.

Do they smell? Mildly, and far less than bully sticks. Most buyers report the odor dissipates quickly.

The Verdict

Buy it if you have a moderate chewer and want a budget-friendly, single-ingredient chew you can stock in bulk. The low odor, decent durability, and per-stick cost make this a legitimate value.

Skip it if your dog is a determined power chewer or you’re not willing to supervise chew sessions. This is a good product with a specific audience — know your dog before you commit to 100 of anything.

Rating: 4.2/5 — solid value with a real caveat about size consistency and chew intensity.
