I watched some of their videos on anti bark training and found it very helpful. They helped me to find anti barking products that actually do work. We've had a citronella spray collar for a while, but eventually our Koko being an Aussie Kelpie she soon began to bark through it. Then I discovered The Dog Line had some great products as well as advice. I then purchased the Petsafe Outdoor device for around the house and a Canicalm Sonic Collar. The Collar is fantastic. It works around 98% of the time which is a relief when we are out walking and especially when I walk my son to his bus stop on school days.
