I used tiny pieces of liverwurst to train Buddy outdoors.
This suggestion came from my daughter's trainer for her MinPin.
It worked like a charm. Only give this special treat for training
to potty, never any other time.
I use 2% cheese for Buddy. He eats it once a week.
I stuff 3/4 piece in a bone on Fri nights while I eat Pizza.
He's not heard from for about 1/2 hr.
