Scrub the pig ears well, cleaning them under running tap water.
(I've even scrubbed them with a bit of soap.) Using a pair of sharp, sturdy kitchen scissors, cut the ears into about three pieces each.
Dip or brush each piece of ear with oil, then place them on a baking sheet. As a special treat, you can use peanut oil or coconut oil.
When all ear pieces are dipped or brushed, sprinkle bouillon powder and a *little* bit of salt over the sheet's contents. Be careful not to over-salt them!
(Most of the commercial ones I've bought for my dog send her running to her water dish for a huge drinking orgy after she's finished eating an ear. I think they contain too much salt, not to mention far too big for her small size.) Bake the ear pieces in the oven at a low 250 degrees for five or six hours.
Drain on paper towels.
Feed to your doggie one piece at a time - this is important for small dogs. My dog would happily eat a whole ear all at once, but I doubt it's good for her.
