lol no an Electric collar, we have had some serous issues with him, such as marking, barking non stop, not comming when called and randomly attacking other dogs. all the postive methodes everyone kept reccomending was making him worse, and he was driving su to the point of breakdown, so we bought an e-collar, the Retriever training type, and it has worked an absolute miracle, I havent had to correct him in a long time, but he wears it still just in case, as he does on occasion slip back ointo his previous behaviour.
