I had a Dalmatian that would not wear one of those... We tried, we even doubled up two buster collars with duct tape to make them stronger... He figured out how to break them within 24 hours, After going through over a dozen of them is when I stopped trying... :realcrazy:
He learned to bang them on the doorway when he walked through until they broke and fell off... He didn't like wearing them... :rolleyes:
