I contacted Bark Busters 1.5 yrs ago after my mother read an article in the Washington Post. I have a 4 yr-old Lab/Newfie mix. Needless to say, he is very headstrong and behind the 8 ball on training. When I got him, he was over a year old and no training. I tried through a local big chain pet store, but he didn't get it; the second try was with a local company that is owned by a former police dog trainer, no luck with them. Bogie was still headstrong and wanted it his way. Once Glenda came and explained the Bark Busters method, Bogie was actually responding to the commands. I have had to call Glenda back for walking on leash issues for Bogie. He is getting it and we are now using the Canny Collar, which is great. I just had Glenda come out so I can get my Westie/Cairn mix, Gracie, started on the training. She has responded better than Bogie. Thank you to Glenda and Bark Busters. It's a great training method that works!
