This is an exercise in learning how much it costs to train a dog and how much it costs not to train a dog.

This story reminds me of an airedale I once knew that had a wonderful outdoor doghouse made out of plywood (I typed plywoof -- what a great typo!) and about four feet high. About three weeks after getting it, the doorway had gone from a nice rectangle to an almost four foot circle with tooth marks all around the edge.
