Collagen for dogs: what it does and where to find it naturally

Tendons, ligaments, cartilage and skin are largely built from one protein. That protein is collagen, the main structural protein in connective tissue, so the natural sources for a dog are the cuts made of those tissues: tendons, backstrap, feet, tail tips and skin. Muscle meat has some. The working parts of the animal have a lot.

What does eating collagen do?

It gets digested. Collagen is a protein, and a dog's gut breaks proteins down into amino acids before anything is absorbed. So the collagen in a tendon doesn't arrive at a joint as collagen. It arrives as parts, and the body decides what to do with them. Dogs make their own collagen from those amino acids; collagen as such isn't on the list of nutrients a dog requires (NRC, 2006).

Whether eating it does anything in particular for a dog's joints, skin or coat is not something we can tell you. We describe what's in the cut. We don't promise what it'll do.

Where is collagen found naturally?

In the parts that did the structural work. Tendon is dense connective tissue and almost nothing else: a kangaroo tendon is about as close to a stick of collagen as a treat gets. Backstrap, the beef neck ligament, is collagen and elastin. Feet and tail tips are skin, tendon, cartilage and small bone, so the bone-in rules apply. Muscle jerky has the least.

Which dogs suit these cuts, and how much?

Most adult dogs with a full set of teeth, chosen by size and chewing style. Tendons and backstrap have no bone and dent under a thumbnail, the veterinary dentists' test for whether a chew can crack a tooth (AVDC). Feet and tail tips are for dogs that chew rather than gulp. Chews wait for adult teeth.

There's no daily amount to aim for, because there's no dose. Feed these cuts because your dog likes chewing them, and keep all treats under about 10% of daily food. They give a dog something to work at for twenty minutes or more; what chewing does for teeth is a separate question, with a separate answer. If your dog is stiff, slow or scratching, that's a vet conversation first.

Chew safely. Size it so it can't be swallowed whole, supervise, and take it away once it's small. Very hard chews can crack teeth — not for puppies, seniors or dogs with dental issues. Fresh water always. A treat, not a meal.

We can tell you which tissue a cut is made of. What it does inside your dog is not ours to say. The collagen-rich cuts are in our chews and bones range, one ingredient each.
