Wobbles the best place I have found is the link I have posted....I have used Tripe for years getting dogs ready for weight pulls and I live by the stuff...I have also used the can and the frozen stuff and for me its the same thing....Also the can is a whole lot easier to handle than the frozen stuff...because this stuff smells like shit LOL.....
