Collagen vs Glucosamine for Dogs: Which Is Better for Joint Support?

Hydrolysed collagen provides collagen derived peptides and amino acids and has a growing body of research in dogs with osteoarthritis and mobility concerns.

Glucosamine is an amino sugar involved in the biology of cartilage and has been used in dog joint supplements for decades. Some canine studies have reported positive findings, but broader reviews have found its clinical evidence less convincing, particularly for pain relief.

There has even been a canine study comparing collagen hydrolysate with a form of sulphated glucosamine. Both groups showed improvements in some measures, and the study did not establish a simple universal winner.

For VeraPaws, that leads to a different question:

Why choose between them if they can have different roles within the same formula?

VeraPaws Hip & Joint Collagen For Dogs contains:

• 80% hydrolysed bovine collagen peptides, Types I and III
• 8% hydrolysed marine collagen peptides, Type I
• 5% MSM
• 5% glucosamine sulphate
• 2% chondroitin sulphate

That means 88% of the formula is collagen.

What Is the Difference Between Collagen and Glucosamine?

It is easy to place collagen and glucosamine in the same bucket because both appear in joint supplements.

But nutritionally, they are quite different.

Collagen

Collagen is a structural protein found throughout connective tissues including cartilage, tendons, ligaments and bone.

Hydrolysed collagen has been broken down into smaller peptides.

After digestion, collagen hydrolysates are absorbed largely as amino acids and smaller peptides. A recent veterinary review describes a developing body of canine evidence around collagen hydrolysates and joint support, while also noting that dosing and clinical research still need improvement.

Glucosamine

Glucosamine is an amino sugar naturally involved in the production of molecules found within cartilage and other connective tissues.

It has become one of the most familiar ingredients in dog joint supplements.

But familiarity is not the same thing as certainty.

Glucosamine has been studied in dogs, and some trials have reported positive findings. Broader evidence reviews, however, have been less convincing about its effectiveness for osteoarthritis pain.

So before asking:

“Which one is better?”

it helps to recognise:

Collagen vs Glucosamine at a Glance

What Does the Research Say About Collagen for Dogs?

The canine collagen evidence has become more interesting in recent years.

A veterinary review published online in 2024 examined the available research into collagen hydrolysates for dogs with osteoarthritis.

It identified several canine studies reporting improvements in areas such as lameness, mobility and quality of life, while also highlighting important limitations including small numbers of studies, different collagen preparations and inconsistent dosing.

One of the newer studies was published in PLOS ONE in 2024.

Thirty one dogs with naturally occurring osteoarthritis completed the study.

Dogs receiving a specific bioactive collagen peptide preparation for 12 weeks showed improvements in several force plate gait measures, and owners reported improvements in quality of life.

Daily activity measured with accelerometers did not significantly improve.

That is encouraging.

But it is important not to turn one specific collagen preparation into proof for every collagen powder.

What Does the Research Say About Glucosamine for Dogs?

Glucosamine has been used in joint supplements for much longer.

And there are individual canine studies that produced encouraging results.

A randomised double blind multicentre trial involving 35 dogs with osteoarthritis compared a glucosamine hydrochloride and chondroitin sulphate combination with carprofen.

Dogs receiving glucosamine and chondroitin showed statistically significant improvements in veterinarian assessed pain, weight bearing and condition severity by day 70, although the onset of response was slower than with carprofen.

So there is canine evidence supporting glucosamine containing formulations.

But that is not the whole picture.

A 2022 systematic review and meta analysis looking at nutraceuticals and therapeutic diets for canine and feline osteoarthritis found little support for glucosamine and chondroitin nutraceuticals as effective pain management interventions.

These findings are not necessarily contradictory.

They tell us that:

Has Collagen Been Compared Directly With Glucosamine in Dogs?

Yes.

And this is one of the most useful studies for this comparison.

A 2021 study included 52 dogs with early osteoarthritis and divided them between:

• collagen hydrolysate
• sulphated glucosamine
• a therapeutic joint diet

The dogs were followed for 16 weeks.

The collagen group included 20 dogs.

The glucosamine group included 21 dogs.

The therapeutic diet group included 11 dogs.

The study reported improvements across the treatment groups in measures relating to mobility, lameness, pain and quality of life.

The authors considered the effects of collagen hydrolysate and sulphated glucosamine broadly comparable for several outcomes, although they described particularly promising findings for the collagen hydrolysate group.

The later veterinary collagen review summarised the same study as showing significant reductions in lameness symptoms in both the collagen hydrolysate and sulphated glucosamine groups.

Does That Prove Collagen Is Better?

No.

The study does not give us a clean basis for declaring one ingredient universally superior.

But it does tell us something important:

So Which Has Better Evidence?

If you are looking for a simple answer, this is where supplement marketing can become misleading.

The evidence is different for each ingredient.

The Practical Answer

The current evidence does not justify saying every dog should receive collagen instead of glucosamine, or glucosamine instead of collagen.

And that is one reason VeraPaws does not treat them as competing ingredients.

Why VeraPaws Starts With Collagen

When we developed the Hip & Joint formula, we could have made glucosamine the main story.

It is familiar.

Dog owners recognise the word.

Many joint supplements are built around it.

We chose a different structure.

Collagen Is the Foundation.

VeraPaws Hip & Joint Collagen For Dogs contains:

80% Hydrolysed Bovine Collagen Peptides

Types I and III.

8% Hydrolysed Marine Collagen Peptides

Type I.

Then we add:

• 5% MSM
• 5% Glucosamine Sulphate
• 2% Chondroitin Sulphate

That means glucosamine has a meaningful place in the formula.

But it is not being asked to carry the entire formula.

Why Not Just Use Glucosamine Alone?

This is where the evidence influenced our thinking.

Glucosamine has a long history in dog joint supplements.

But the broader research is mixed.

That makes us reluctant to build the entire joint formula around glucosamine and then treat everything else as an afterthought.

Instead, VeraPaws uses:

collagen as the nutritional foundation

with

glucosamine, MSM and chondroitin as supporting ingredients.

Why Include Glucosamine at All?

Because mixed evidence does not mean an ingredient has no nutritional rationale.

Individual canine trials have reported improvements with glucosamine containing formulations, and glucosamine remains a well established ingredient in joint nutrition research.

For VeraPaws, the question is not:

“Is glucosamine perfect?”

It is:

“Does glucosamine have a sensible role within the complete formula?”

We believe it does.

That is why the Hip & Joint formula contains 5% glucosamine sulphate.

It is there as part of the formula.

It is not the whole formula.

What About Chondroitin?

Glucosamine is frequently paired with chondroitin.

Chondroitin is another compound associated with cartilage and connective tissue and has also been studied in joint supplements.

Many glucosamine studies actually evaluate glucosamine and chondroitin together, which is important when interpreting the evidence.

For example, the 2007 canine study reporting positive findings did not test glucosamine alone. It tested a glucosamine and chondroitin combination.

The Hip & Joint formula contains:

2% chondroitin sulphate

alongside:

5% glucosamine sulphate

Again, the idea is not that one ingredient must do everything.

And Why MSM?

MSM is an organic sulfur compound commonly used in joint formulas.

It has a different role from both collagen and glucosamine.

Hip & Joint includes 5% MSM as another supporting ingredient within the complete formula.

The VeraPaws Hip & Joint Collagen For Dogs Formula at a Glance

Joint supplements should be compared by more than ingredient names.

Ask:

“What actually makes up most of the formula?”

With Hip & Joint, the answer is clear.

Collagen.

Australian Collagen Is Part of the Formula Story

The collagen foundation also has a clear provenance.

VeraPaws uses Australian grass fed hydrolysed bovine collagen alongside wild caught marine collagen peptides made in Australia.

That does not make the collagen clinically better simply because it is Australian.

But it does give Australian dog owners clearer information about what they are buying and where the collagen behind the formula comes from.

It is another reason we believe product comparison should go beyond a familiar ingredient name on the front of the pouch.

Can Dogs Take Collagen and Glucosamine Together?

Yes.

There is no general reason these ingredients have to be treated as mutually exclusive.

They are already combined within the Hip & Joint formula.

What matters is understanding the complete formula and avoiding unnecessary overlap if your dog is already taking several supplements.

For example, if your dog already receives a separate:

• glucosamine supplement
• MSM supplement
• chondroitin supplement
• multi ingredient joint product

check what they are already receiving before adding another formula.

If your dog takes medication or has an existing medical condition, discuss supplement combinations with your veterinarian.

Why Dog Weight Matters

Ingredient names are only part of the comparison.

Serving matters too.

A 5 kg dog and a 35 kg dog are very different sizes.

That is why VeraPaws serving guidance changes according to dog body weight.

One level teaspoon is approximately 3 g.

For Hip & Joint, 88% of that serve is hydrolysed collagen.

These are VeraPaws serving instructions, not universal scientifically established doses for collagen or glucosamine.

For complete instructions, see our collagen serving guide for dogs.

What Should You Compare When Choosing a Joint Supplement?

Is Collagen Better for Senior Dogs?

Not automatically.

Age alone does not tell you which supplement will suit an individual dog.

Senior dogs may be more likely to experience changes in mobility, but those changes can have many causes.

The useful question is not:

“Is collagen or glucosamine better because my dog is old?”

It is:

“What is causing the change in movement, and what kind of support does this dog actually need?”

Persistent stiffness, limping, difficulty rising or obvious pain deserves veterinary assessment.

A supplement can be part of the routine.

It should not replace finding out why the dog is uncomfortable.

What About Dogs With Arthritis?

Both collagen and glucosamine have been studied in dogs with osteoarthritis.

But neither should be described as a cure for arthritis.

The evidence for nutraceuticals is variable, and osteoarthritis management is generally broader than one supplement.

For a dog with diagnosed osteoarthritis, nutritional supplements may sit alongside:

• appropriate body weight
• suitable exercise
• rehabilitation
• environmental changes
• veterinary pain management

The 2022 systematic review is particularly important here because it evaluated nutraceutical evidence in the context of osteoarthritis pain, rather than simply asking whether an ingredient has a plausible biological role.

Premium Collagen For Dogs or Hip & Joint Collagen For Dogs?

This is an important VeraPaws distinction.

Premium Collagen For Dogs

Premium contains:

• 90% hydrolysed bovine collagen peptides, Types I and III
• 10% hydrolysed marine collagen peptides, Type I

It is our straightforward everyday collagen for dogs formula.

There is no glucosamine, MSM or chondroitin added.

Hip & Joint Collagen For Dogs

Hip & Joint contains:

• 80% hydrolysed bovine collagen peptides, Types I and III
• 8% hydrolysed marine collagen peptides, Type I
• 5% MSM
• 5% glucosamine sulphate
• 2% chondroitin sulphate

If your goal is a simple everyday collagen routine, Premium may be the better fit.

If you are specifically looking for a formula built around movement and joint support, the Hip & Joint formula adds targeted supporting ingredients around the collagen foundation.

So, Collagen or Glucosamine?

If you came here expecting one word, the research does not really give us one.

Collagen has an increasingly interesting canine evidence base.

Glucosamine has positive individual studies and a long history in joint supplements, although broader reviews have questioned how consistently it improves osteoarthritis pain.

And at least one canine study has examined collagen hydrolysate and sulphated glucosamine within the same research program, with improvements reported in both groups.

So for VeraPaws, the answer is not:

Collagen or Glucosamine?

It is:

Collagen and Glucosamine, With Clearly Different Roles.

We make collagen the foundation.

We use glucosamine as part of the supporting formula.

That is the thinking behind the Hip & Joint formula.

What Australian Dog Owners Should Remember

If you are comparing collagen and glucosamine for your dog, look beyond the ingredient names.
