Collagen sticks and bully sticks are both single-ingredient beef chews from different parts of the cow. Bully sticks are dried beef pizzle (muscle); collagen sticks are corium, the collagen-rich inner layer of cowhide. Bully sticks digest a little faster; collagen sticks usually last longer and scrape teeth more. Neither is a dosed supplement — so if what you really want is measurable joint, skin and coat support, Pure Majesty Pets Liquid Collagen for Dogs, the most popular liquid collagen for dogs, gives you 462 mg of hydrolysed collagen I & III and 48 mg of UC-II in every 2 mL. It is A$47 a bottle with free worldwide shipping, and Australian orders arrive with duties and GST prepaid.
What's the difference between collagen sticks and bully sticks?
The split comes down to the raw material. A bully stick is made from beef pizzle — a cleaned, slow-dried bull muscle that is a by-product of the beef industry. A collagen stick is made from the corium, the innermost layer of cowhide that is naturally dense in Type I and Type III collagen, then minimally processed (air-dried or lightly baked) to keep that protein structure intact.
Both are high-protein, low-fat, and free of the artificial binders found in many processed treats. Australian shoppers will find both on the shelves at Petbarn, Petstock, PetO and Pet Circle, in sizes from thin 15 cm sticks to thick braids. The practical differences a dog owner actually notices are chew time, texture, digestibility and kilojoules. If digestive signs are driving this decision, keep parasite testing in the conversation too: the dewormer coverage guide explains why a supplement label and confirmed parasite coverage are different things.
Collagen sticks vs bully sticks at a glance
| Feature | Bully sticks | Collagen sticks |
|---|---|---|
| Source | Beef pizzle (muscle) | Corium — inner layer of cowhide (Type I & III collagen) |
| Protein | Very high (roughly 80–97%) | High (collagen protein) |
| Fat | Low (roughly 1–5%) | Low |
| Energy | ~370 kJ (88 kcal) per 15 cm stick (published range ~190–560 kJ by size/density) | Varies by size; treat as energy-dense, factor into daily total |
| Chew time | Moderate; softens as it's chewed | Often longer — some brands cite ~20% longer, ~30–55 min of chewing |
| Digestibility | Breaks down readily in stomach acid | Highly digestible, but generally slower to break down than a bully stick |
| Dental action | Some scraping; softens quickly | Firmer, elastic texture — more sustained tooth-scraping |
| Odour | Can be strong (even "odour-free" varies) | Usually milder |
Energy and digestibility figures are typical industry ranges, not guarantees — density varies by brand and stick size. Always check the label and adjust your dog's meals.
Which is more digestible — and safer for sensitive stomachs?
Both chews are far more digestible than rawhide, which is the reason most owners switch. Bully sticks break down predictably in stomach acid, so if a dog gulps a chunk it usually passes without trouble — a point in their favour for enthusiastic gulpers. Collagen sticks are also close to fully digestible, but they break down more slowly than bully sticks, so a large swallowed piece sits longer.

For a dog with a genuinely sensitive stomach, a fast-digesting bully stick can be the gentler pick. For a power chewer who tends to bite off and swallow chunks, the safest move with either chew is correct sizing and supervision, not the material alone. In an Australian summer, also keep chew sessions in the shade with fresh water nearby: a long, vigorous chew on a 35 °C afternoon makes a dog pant and drink more, and RSPCA Australia advises keeping activity to the cooler parts of the day.
Do collagen sticks or bully sticks clean a dog's teeth better?
Chewing helps mechanically wipe soft plaque off tooth surfaces and stimulates saliva, and collagen sticks tend to hold their shape longer, so they give a more sustained scraping action than a bully stick that softens quickly. That's a modest, real benefit — but it is not a substitute for brushing or a veterinary dental clean. No chew reaches below the gumline where periodontal disease starts. Treat "cleaner teeth" as a nice side effect of longer chewing, not a dental routine on its own.
If dental health is the main goal, Australian owners often add a water additive or a plaque powder — Pet Circle's dental range includes Troy PlaqueOff Dental Powder (A$49.99 for 40 g), Petz Park Plaque Control Powder (A$34.49) and Oxyfresh Dental Water Additive (A$22.99 for 250 mL) — alongside brushing. We put the chew claim under the microscope in a separate breakdown of do collagen chews clean dogs' teeth, including what the plaque and tartar research actually measures.
What about "collagen bully sticks" — are they good for dogs?
"Collagen bully sticks" is mostly a marketing label. In practice it usually means a collagen stick (corium) shaped or braided to look like a bully stick — not a bully stick with collagen added. They're a reasonable chew for the same reasons any quality collagen stick is: single-ingredient, digestible, long-lasting. The name matters less than three things: what it's actually made of (look for a single named protein), where it's sourced and inspected, and whether it's the right size for your dog. Australian-made treats may also carry accreditation under AS 5812, the voluntary Australian Standard for the manufacturing and marketing of pet food, run by the Pet Food Industry Association of Australia (PFIAA).
Do these chews actually deliver joint and skin benefits?
Here's the part most chew pages skip: a collagen stick delivers structural Type I and Type III collagen for chewing enrichment and a little dental help, but the amount your dog actually digests and absorbs for joints, skin or coat is undefined and uncontrolled. You can't titrate a chew to your dog's weight, and a Type I chew does not contain the undenatured Type II (UC-II) collagen that the joint research actually studied.
What the evidence looks at is measured collagen supplementation, not chews. Studies suggest hydrolysed collagen and undenatured type II collagen may support joint comfort and mobility in dogs — for example, work on collagen-based supplements by D'Altilio and colleagues (Toxicology Mechanisms and Methods, 2007;17:189–196), a force-plate study by Gupta and colleagues (Journal of Animal Physiology and Animal Nutrition, 2012;96:770–777), and a 2021 trial in Labradors by Varney and colleagues on undenatured type II collagen, inflammation and cartilage markers (Translational Animal Science, 2021;5(2):txab084, PMID 34124592). These used defined doses of specific collagen forms, which a chew can't promise. Current research does not show that any chew, by itself, delivers a meaningful joint dose. The separate guide, Gupta 2012: How 10 mg of UC-II Beat 3,600 mg of Glucosamine + Chondroitin in Dogs (Force-Plate Confirmed), explains the choices in more detail.
That's the practical dividing line. If you want a chew for enrichment, cleaner teeth and a rawhide-free way to keep a dog busy, a good collagen stick or bully stick is a fine choice — and our guides on collagen sticks for dogs and collagen vs rawhide go deeper on picking one. If your goal is measured joint, skin and coat support you can dose to your dog's weight, that's a supplement's job, not a treat's.
Why a dosed liquid beats a chew for joint support
This is where a dosed format is a different tool. Pure Majesty Pets Liquid Collagen for Dogs delivers, per 2 mL serving:
- 462 mg hydrolysed collagen types I & III — the same collagen family as a corium chew, but in a known amount;
- 48 mg UC-II (undenatured type II collagen) — the joint-specific form a beef chew doesn't provide;
- 252 mg salmon oil + bone broth complex;
- 73 mg L-glutamine + postbiotic complex;
- 71 mg MSM + hyaluronic acid complex;
- 9 mg vitamin C + ginger + astaxanthin complex.
It's sugar- and xylitol-free, made in a GMP facility, with a certificate of analysis for every batch. Compare that with the joint chews on Australian shelves — PAW by Blackmores Osteocare (A$41.99 for 300 g at Petbarn) or Vetalogica Canine Joint Support (A$33.99 for 120 chews) — which bring their own kilojoules and are built around glucosamine rather than collagen plus UC-II. A chew entertains; a measured dose is what you reach for when the outcome, not the chew time, is the point. Plenty of owners do both: a bully or collagen stick a few times a week for enrichment, and a daily 2 mL of liquid collagen on dinner. Comparing collagen with another joint ingredient? The glucosamine buying guide shows how to compare glucosamine forms, measured amounts and combination products.
How do I choose a chew safely, especially for small dogs?
Size and supervision matter more than the collagen-versus-bully debate. Match the chew's thickness and length to your dog's weight and chew style: thin or standard for small breeds and light chewers, thicker for large or power chewers. Take the chew away once it's worn down to roughly 6–8 cm so it can't be swallowed whole, and never leave a dog chewing unsupervised — choking and intestinal blockage are the two real risks with any edible chew. Small dogs should have chews sparingly and always sized down. If your dog gulps rather than gnaws, a faster-digesting bully stick plus close supervision is the more forgiving combination.
For frequency, energy load and how chews fit alongside a daily supplement, see our collagen dosage and side effects guide, the full collagen for dogs pillar, and our roundup of the best collagen for dogs. You can also compare collagen supplements for dogs if you're weighing a chew against a dosed format.
Chew size matters more the smaller your dog is. If you have a toy or small breed, see our guide to collagen for small dogs for dosing by kilogram and safe chew sizing.

For that, order Pure Majesty Pets Liquid Collagen: 462 mg collagen I & III plus 48 mg UC-II per 2 mL, A$47, free shipping to Australia with duties and GST prepaid, nothing to pay on delivery.
Frequently asked questions
Are collagen sticks or bully sticks better for dogs?
Neither is universally better. Bully sticks digest a touch faster and suit sensitive stomachs and gulpers; collagen sticks usually last longer and give more sustained tooth-scraping. Both are single-ingredient beef chews and both need correct sizing and supervision.
Are collagen bully sticks good for dogs?
Generally yes, when they are single-ingredient and properly sized. Collagen bully sticks usually means a corium collagen stick shaped like a bully stick. Judge it by its actual ingredient, sourcing and size rather than the name.
Do collagen sticks give my dog joint benefits?
A chew provides structural collagen for chewing enrichment, but the absorbed amount is undefined and it lacks the undenatured Type II (UC-II) collagen studied for joints. For measured joint support you can dose to weight, a supplement is the more reliable tool.
Which lasts longer, a collagen stick or a bully stick?
Collagen sticks typically last longer, with some brands citing around 20% more chew time, because the corium holds its firm, elastic texture while a bully stick softens as the dog works it.
Are these chews safe for small dogs?
They can be, with thin or standard sizing and constant supervision. Small breeds should have chews sparingly, and you should remove any chew once it is small enough to swallow whole to avoid choking or blockage.
Can I buy Pure Majesty Liquid Collagen in Australia?
Yes, direct from our Australian store. Shipping is free worldwide and orders to Australia ship with duties and GST prepaid (DDP), so there is nothing to pay on delivery. A bottle is A$47.
