As the other reviewer says, far more brittle than the nice, chewy green. My dogs are large and love their food ( they'll happily eat raw eggs, shell and all) but my male really isn't keen on this. He'll look around for something - anything - better, but watching my bitch eating it and knowing she'll eat his he eventually eats it. Even my 50kg, greedy beast of a bitch clearly doesn't relish it.
Unlike the green tripe this shatters as soon as my Staffie bites it, a bit like a dog version of a popadom. I only feed him it outside but he does like it, it isn't greasy and it doesn't smell,
