In a medium size bowl combine eggs, bacon grease or coconut oil and mashed banana.
Add in flour, almond flour (or cornmeal), oats, and peanut butter. Mix until combined, it will look like a thick cookie batter.
Sprinkle flour on your work surface and roll dough to ¼” thick. Use cookie cutters to cut out the dog treats*.
Place the treats on dehydrator mats, spaced out so they aren't touching. The dough will not spread. Set dehydrator to 145 F degrees, rotate the trays at 4 hours and check at 8 hours. The treats may take up to 12 hours depending on humidity.
Notes
If the dough is too sticky to roll try rolling it out between two sheets of parchment paper.
*Cut the treats into sizes that are appropriate for the size of your dog, i.e. the treats should be the size of the treats your dog normally receives.
Store treats in an air-tight container or you can freeze them in a ziptop bag for up to 3 months.
See the post for details on oven drying your DIY treats.
