Hi Marie-

I buy K9 frozen tripe at our local feed store. It also comes in freeze dried form as well. Here is a link: http://www.k9natural.com/dog-food/type/frozen/frozen-lamb-green-tripe-1kg-106-fr-1kg-dom-k9n

I think some people buy it from butchers too. I either add egg, sardines, tripe, commercial raw or canned food to all their meals. Hope you find something that works!
