Owner Tom Long has a geese mitigation business called Goosebumps.
The dog chases away Canada geese, which are a protected species.
Long says the dog doesn't attack the birds, he just barks at them and scares them away.
He recently demonstrated John's abilities at Caterpillar in the Lafayette, Indiana, area.
Company officials tell the Journal and Courier the geese are making a mess of their property.
