I use them for training. I also don't like the wheat and sugar, and HK gets skin rashes from wheat. But I cut them into 1/4 cubes and she really doesn't get much in a day. This rate hasn't created the rash problem.
I have looked for something like you are seeking. About all I have found is hot dogs or sausage for peeps. But them for my convenience, have to bake or microwave them down to get rid of all that moisture. i.e. I don't like the wet squishy in my pocket.
