What is tripe?
The four types, green versus white, how cooks use it, and where dogs come in.
Last updated
Tripe is the lining of the stomach of cattle and other ruminants (cud chewing animals), prepared as edible offal. Wikipedia defines it that way and says most tripe comes from cattle and sheep, with goats, deer and other ruminants less common (Wikipedia, Tripe, used only for the definition and the culinary names, opened 2026-10-16). "Beef tripe" means it came from a cow. People eat it in many cuisines, and it is also sold for dogs, raw, frozen, dried or freeze-dried.
Why a cow has four stomach chambers
A cow has one stomach with four compartments. South Dakota State University Extension describes them: the rumen is the largest, holding 25 to 50 gallons depending on the animal, and is full of microbes that ferment feed. The reticulum has a honeycomb texture. The omasum has folded tissue that resembles book pages and absorbs water from the feed. The abomasum is the "true stomach," with smooth, mucus covered tissue and acid (SDSU Extension, Ruminants: digestive powerhouse, opened 2026-10-16). Each chamber looks different, and that is why tripe comes in different types.
The four types of tripe
Cooks name tripe by the chamber it comes from, and Wikipedia lists the pairings:
| Chamber | Name in the kitchen | What it looks like |
|---|---|---|
| Rumen | Blanket, flat or smooth tripe | Thick, flat, smooth sheets |
| Reticulum | Honeycomb or pocket tripe | A raised honeycomb pattern |
| Omasum | Book, bible or leaf tripe | Many thin folds, like pages |
| Abomasum | Reed tripe | Seen less often because of glandular tissue |
Honeycomb is the one in most food photos. An SBS Food recipe for slow cooked honeycomb tripe describes it as looking "like a bathing cap with its crazy patterning" (SBS Food, Slow cooked honeycomb tripe, opened 2026-10-16). A package of tripe often does not say which chamber it is, and a pet food label that says only "beef tripe" does not either. Ours is labeled beef tripe, and we do not name a chamber.
Green tripe and white tripe
The color difference comes from what happens after slaughter, not from two different animals.
White (dressed) tripe is what a butcher case usually holds. Wikipedia says dressed tripe has been cleaned, trimmed of fat, then boiled and bleached, which is where the pale color comes from.
Green tripe is the unprocessed version. In the Whole Dog Journal's usage, "green" means the stomach lining was sold raw and left unprocessed, and the article notes that the tissue usually looks brown, with only a greenish tint (Whole Dog Journal, Green Tripe for Dogs, opened 2026-10-16). The same article is blunt about the smell, and it is the reason raw green tripe usually lives in a freezer.
Our freeze-dried tripe is green tripe, meaning unbleached beef tripe that is freeze-dried raw. The longer explanation is on the green tripe for dogs page.
How cooks prepare tripe
Tripe is tough until it is cooked for a long time. The SBS recipe above simmers honeycomb tripe gently in water and vinegar for 30 minutes first, then drains and rinses it, slices it and braises it for about another hour. Cooks pair that long simmer with strong flavors, and the dishes Wikipedia names include French tripes a la mode de Caen, Spanish callos, Italian trippa alla romana and Korean gopchang jeongol. If you ever cook tripe for people, follow a tested recipe and the usual kitchen hygiene rules. None of that applies to the dog treat in our bag, which is not cooked.
Tripe and dogs
Tripe is also sold as pet food and treats. You will find it frozen raw, ground, dried and freeze-dried. Ours is a treat or topper, not a complete diet. We do not make medical claims for tripe, and we are not going to repeat the claims others make. What we can tell you is what is on our label and what the named sources say.
- Raw means care. VCA cites a screening where close to one in four raw food samples carried harmful bacteria such as Salmonella and Listeria monocytogenes, and it asks owners who feed raw to tell their vet (VCA, Dogs and Raw Food Diets, opened 2026-10-16).
- Handling. The FDA tested 196 raw pet food samples and found Salmonella in 15 and Listeria monocytogenes in 32. Its advice is to wash your hands for at least 20 seconds after handling raw pet food and to clean what it touched (FDA, Get the Facts! Raw Pet Food Diets can be Dangerous to You and Your Pet, opened 2026-10-16).
- What freeze-drying does. Removing water lowers a food's water activity, which the University of Minnesota Extension explains in its guide to drying food (UMN Extension, Preserving food at home: Drying, opened 2026-10-16). That is why the bag keeps on a shelf. Our tripe was still raw before drying, so the handling advice stays.
Our label lists one ingredient, beef tripe, and the listing is for adult dogs, medium and large, as a treat or topper and not a complete diet. Sniff and Shift also sells freeze-dried beef liver, and the Beef Trio set includes it. Read can dogs eat tripe for the full sourcing, and how to feed tripe for amounts and storage.
Questions about tripe
What is tripe made of?
Tripe is the lining of a ruminant's stomach, most often a cow's or a sheep's, prepared as edible offal. Beef tripe means the stomach of a cow.
What animal is tripe from?
Mostly cattle and sheep, and sometimes goats, deer and other ruminants. Beef tripe, the kind on our label, comes from cattle.
What are the types of tripe?
Four, named for the chamber they come from: blanket tripe from the rumen, honeycomb from the reticulum, book or leaf tripe from the omasum, and reed tripe from the abomasum.
What is the difference between green tripe and white tripe?
White tripe has been cleaned, boiled and bleached. Green tripe is sold raw and unprocessed, and the Whole Dog Journal notes that it usually looks brown with a greenish tint. Ours is green tripe, freeze-dried raw.
Why does tripe smell so strong?
The Whole Dog Journal puts it plainly: "This stuff really stinks." Freeze-drying makes ours quieter than raw tripe, and our own scorecard still rates the smell strong.
Can dogs eat tripe?
Many owners feed it, but it is a raw product, so VCA and the FDA advise care in handling it, and a treat is not a complete diet. Ask your vet whether it suits your dog. See can dogs eat tripe.
Is the tripe in your bag cooked?
No. It is raw beef tripe that has been freeze-dried, with no other ingredient on the label, so wash your hands after handling it.
