Need recipe for horse treats and saddle soap

As the title says, but am looking for a recipe similar to Mrs. Pasture’s treats. Something crunchy. How long can they be kept. I’ve seen some recipes with egg, applesauce, and carrots, and did not think these would keep well.
Also need an easy saddlesoap one. I had a recipe last year that contained glycerine that you melted in the microwave with other ingredients, (maybe murphys oil soap, or lexol) and poured into gladware, but can’t find it for the life of me.
Some recipes I’ve looked at also contain milk? and I didn’t think they would last long either. TIA

These are pretty good - they can be baked a little longer to make them drier and last longer: http://allnaturalpetcare.com/blog/2012/09/25/dog-or-horse-treat-recipe-easy-crunchy-pumpkin-apple-cookies/
I use oat flour or just process a bunch of oats to a flour consistency instead of green pea flour.

I also like the first two here:

Don’t know about the saddle soap, but I would love to hear the responses.
