Collagen for Dogs: The Key to Healthy Joints, Skin and Digestion

Just like humans, dogs benefit from collagen at every stage of life. Puppies need it to support growth and strong bones. Adult dogs thrive on it for a healthy coat, gut and teeth. And senior dogs rely on collagen to keep their joints mobile and pain-free.

At home, we make sure Lenny enjoys collagen rich foods every day to support his joints, coat and gut health. Lenny has always had a sensitive tummy. It has made a real difference in keeping him strong, full of energy and the same can be true for your furry friend.

What is Collagen and Why Does Your Dog Need It?

Collagen is the most abundant protein in your dog’s body. It builds and supports joints, muscles, tendons, skin, coat and even the lining of the digestive system. Around 30 percent of your dog’s total protein is made up of collagen.

As dogs age, their natural collagen production slows down. This can lead to stiffness, brittle nails, dry skin, dull coats and sensitive tummies. Adding collagen back into their diet is one of the best ways to support long term health.

Signs Your Dog May Need Collagen

If you notice any of these changes, your pup may benefit from extra collagen:

• Limping or stiffness after walks
• Struggling with stairs or jumping
• Fatigue or slowing down on walks
• Dry, itchy skin or a dull coat
• Sensitive digestion or tummy upsets
• Dirty teeth or thin gums

5 Benefits of Collagen for Dogs

1. Supports Joint Health and Mobility

Collagen cushions joints and helps repair connective tissue. Research shows it can improve flexibility and reduce discomfort in dogs with early arthritis.

2. Promotes Healthy Skin and Shiny Coats

Collagen makes up about 70 percent of your dog’s skin protein. It keeps skin hydrated, reduces itchiness and helps maintain a thick, glossy coat.

3. Aids Digestion and Gut Health

Collagen is rich in amino acids like glycine, which help strengthen the gut lining and support smooth digestion.

4. Strengthens Teeth and Bones

Chewing collagen rich treats naturally scrapes away plaque while collagen proteins keep teeth and gums strong.

5. Boosts Energy and Recovery

Collagen supports muscle repair and growth, making it especially helpful for active or working dogs who need recovery after exercise.

Best Natural Sources of Collagen for Dogs

Collagen powders and supplements exist, but many dogs benefit most from natural, whole-food sources that also double as tasty enrichment. Some excellent options include:

• Bone Broth – Slow-cooked from bones, it’s one of the richest and most easily absorbed sources of collagen. Perfect for pouring over meals or serving as a warm treat.
• Duck Feet – Crunchy and naturally packed with collagen, ideal for joint support and dental health.
• Shark Cartilage – A natural source of collagen plus glucosamine and chondroitin for mobility.
• Bully Sticks – Long-lasting chews that promote dental hygiene while supporting joint care.
• Bones – Raw marrow bones are rich in collagen, calcium, and essential minerals to support strength and vitality.
• Fish Skin – Light, crunchy, and loaded with both collagen and omega-3s to keep skin and coats healthy.
• Eggs – The membrane inside eggshells is an underrated source of collagen that supports joint health.

At Lenny’s Pup Shop, we love offering natural collagen-rich chews like duck feet, shark cartilage, bully sticks, and bones because they don’t just nourish — they keep dogs happy and engaged.

Are Collagen Chews Safe for Dogs?

Yes, collagen chews are generally safe and easy to digest. To keep your pup safe:

• Choose single ingredient chews with no fillers or chemicals
• Pick the right size chew for your dog’s breed and chewing style (check out our chew guide here)
• Always supervise chewing to prevent choking hazards

At Lenny’s Pup Shop, we only stock natural Australian made collagen rich chews that are safe and healthy.

Collagen Supplements vs Natural Chews

Powdered collagen supplements can be effective, but natural chews offer extra benefits:

• Chewing action keeps teeth clean
• Whole foods provide extra vitamins and minerals
• Easier on sensitive tummies

Most dogs will benefit from a combination of balanced meals and collagen rich chews.

Should You Ask Your Vet First?

It is always smart to check with your vet before introducing new treats or supplements, especially if your dog has allergies or medical conditions. For example, avoid beef-based collagen if your dog has a beef allergy.

The Bottom Line

Collagen is a simple but powerful way to keep your dog healthy at every life stage. It supports joint health, improves skin and coat, aids digestion and helps keep teeth strong.

The easiest way to add collagen to your dog’s diet is through natural chews like duck feet, shark cartilage, bully sticks and bones. These treats are safe, tasty and packed with natural collagen that your pup will love.
