Lucky you Steph! This is what I do. I get a bunch of gallon freezer bags and have them open ready to fill. I spread the tripe out on a tarp outside and hose it off to get the big junk out. This takes some time as you will be wrestling with it to turn it over and inside out.
Then Kitchen shears! I cut into chunks and fill each bag about 1/2 way. This I will mix with other raw stuff so each bag is a day or two's worth of tripe for my three dogs. Yes I feed lungs. I cut and package it the same way.
Messy, stinky, disgusting stuff the dogs love.
