85% Protein on a Lamb Collagen Chew: Jaw Work, Not a Meal

85% protein on a lamb collagen chew is a fact about the tissue, not about your dog's diet: the stick is one layer of lamb skin, and that layer is mostly collagen. Jaw work, not a meal. The bowl is still the diet.

Every collagen chew page in the aisle leads with the protein number and stops there. None of them says what collagen protein is made of, which is the part that decides whether the number touches a diet you already got right. This page gives that composition, then says what it settles and what it does not.

Why a single-ingredient lamb chew posts a number that high

Nothing was added to dilute it. Crude protein on a chew label is a guaranteed minimum, and the stick behind it is one tissue: the corium, the collagen layer of lamb skin. It is braided, slow oven-dried, and never coated or treated. Moisture is capped at 14%. Take the water out of one tissue and most of what remains is the protein itself.

That figure sits on one tissue, and the layer it is cut from is described in full elsewhere. The badge sits above the title on our 6-inch lamb collagen sticks, with the guaranteed analysis it comes from further down the same page.

Which fields a bag has to print, and which it may leave off, has its own page on what a chew label has to carry. This page does not re-run it. The number is the subject here, not the panel it sits in.

What collagen protein is built from

Collagen is not a generic protein with a high score. It has a specific ratio, and it is well measured in the human nutrition literature. A narrative review of collagen protein puts glycine at about a third of it — roughly 33% — with proline near 10% and hydroxyproline at 13.5%.

There is a reason for the ratio. Glycine sits in every third position along the chain, which is what lets three strands pack tightly enough to hold, and the repeating unit is written Gly-Pro-X. The protein had a shape and a job long before it had a percentage.

The table describes collagen, not our stick. We publish no amino acid assay for a Foodiepaws lamb collagen chew, and these figures come out of the human nutrition literature. Read them as a description of the material the braid is made of. The last row is the one that gets misread — the next two sections are about it.

Structure protein and food protein are not the same job

Collagen is what holds tissue together. It is the principal material of the layer the chew is cut from, and its job in a living sheep is tension. Skin that does not tear, tendon that does not stretch. A protein built to be a cable is not the same object in a nutrition column as a protein built to be eaten. Same word, different work.

That is also why a collagen chew is not a supplement. What the joint trials actually dosed has its own page, and the answer there is jaw work rather than a dose.

The percentage is a composition figure, and composition figures describe material rather than nutrition. Two things made of one material can be built for opposite purposes. What the panel reports is what the tissue was at the point it went into the bag.

The amino acid that is not in there, and what that settles

The gap is scoring, not safety. The same review is blunt about that end of the profile: every collagen type contains no tryptophan. Nutrition researchers who put the number at one — one indispensable amino acid short — went on to model how much collagen a human diet can carry anyway. They landed at up to 36% of dietary protein in people, with indispensable amino acid requirements still met.

That figure is human dietary modelling and it stays there: not a dog guideline, not a chew allowance. What it settles is the shape of the objection. Being one indispensable amino acid short makes collagen an incomplete protein source on paper — a scoring problem for a food that must carry an entire diet. A chew has never been asked to carry one.

Which is exactly why the number on the bag does not reach the bowl. A protein that scores as a partial source is a poor candidate to replace a meal — and a perfectly ordinary thing to hand a dog between meals. The bag is not competing with the food. It is competing with the afternoon.

85 and 70: two panels, two tissues

Both numbers are minimums. The collagen braid posts 85% crude protein and the tripe stick posts 70%, and the gap between them is not a quality ranking. It tracks what each tissue is. The corium is a collagen sheet; green tripe is stomach lining dried whole. Two tissues, two panels.

The lamb tripe range posts a 6% fat minimum where the braid posts 1%. Beyond the two panels, no composition figure has been published for either lamb tissue, ours included. Neither figure decides which chew you hand over. A dog that ignores everything else takes to the aroma, and that aroma is the reason tripe wins a picky eater.

The higher number is not the better chew. It is the leaner panel, and that is all the gap between 85 and 70 is. Both lengths in the lamb collagen range carry the same panel, because both are the same tissue. The number does not move with the stick. It moves with what the stick is.

What the protein number does not decide

Four things the percentage does not settle. It is not an allergen statement: a percentage says nothing about which protein a dog reacts to, and the animal decides that, not the column. If that is the question you actually came with, the aisle sorted by animal is the page for it.

It is not a joint claim. High in protein is a claim we make; nothing else is built on top of it. It is not a digestibility figure either, and none is published for any chew of ours. And it is not chew time — there is no published chew-time figure for lamb collagen or lamb tripe, ours included.

None of that is a mark against the number. It is a boundary around what a composition figure can do — describe a material, then stop. Ask it what your dog will do with the stick and it has nothing to say.

Where the chew sits in a diet you already balanced

The chew was filed with the treats. WSAVA's definition of a treat names chews on a list of four, alongside snacks, supplements, and foods used to administer medication. The chew was outside the diet arithmetic before anyone read its protein column. Our own feeding steps say the same thing in plainer words: for intermittent or supplemental feeding only, not a complete diet, per AAFCO guidelines.

How much room a treat gets in a day is worked through on the treat ceiling, and this page does not re-derive it. The short version is that the budget is made of calories, not of protein. Whether cutting the bowl on a chew day is warranted depends on calories too. The bowl stays the bowl.

The chew never entered the diet arithmetic, which is why a number that big on the bag can be read and then set down. Nothing in the bowl has to move.

Lamb collagen protein FAQ

What does 85% protein on a dog chew mean?

It means the bag holds one tissue and almost nothing else. Crude protein on a chew is a guaranteed minimum, and a lamb collagen stick is a single layer of lamb skin, braided and dried, with moisture capped at 14%. Take the water out and most of what is left is collagen protein. It describes the stick in your hand, which is why it sits alongside the bowl rather than changing it.

Does a high-protein chew change my dog's diet?

No, and that is the useful part of it. A chew is a treat, not a meal: the WSAVA treat handout lists chews alongside snacks, supplements and foods used to give medication. The Foodiepaws feeding steps say it in plainer words — intermittent or supplemental feeding only, not a complete diet. The bowl stays the bowl, and the chew is counted with the treats.

Which amino acids is collagen highest in?

Glycine, by a distance. Collagen protein runs about 33% glycine, roughly 10% proline and 13.5% hydroxyproline. Glycine sits in every third position along the chain, which is what lets three strands pack tightly into a coil. Hydroxyproline is close to a fingerprint, since very little else carries it. That composition describes collagen itself, which is what a lamb collagen braid is made of.

The number on the front of the bag is honest, and it is honest about the stick rather than about the diet. Buy it for the jaw, not for the protein column. Then take the stub away.
