green tripe

Met someone at the park today who talked about greentripe.com which is here in California (and saw a Dirty Jobs segment ewwww). Is the freeze dried version or jerky treat version just as good? How are the canned versions made - are they cooked? Seems like it's only getting more popular now...

I was lucky enough to find a butcher that could bring in some green tripe for us. Smuckers went a little nuts for it but he wolfed down the portion I gave him yesterday! It was maybe a 1/4 pound section but I wanted to see how he would adjust to it as I've heard some dogs end up with diarrhea...
