My neighbours complained about my barking fur babies waking their children during the night and panic set in!!! I had to do something or risk getting the council involved!! After a search of products online I found The Dog Line and went ahead with renting the "Rent a Bark Collar". Milo (the offending dog) learnt quicksmart that barking had consequences and the barking stopped. It worked so well that I bought it after 2 weeks and still use it on and off when he starts barking again. The only downside was that I spent time racing around the shops looking for batteries but it was only after a call to the Dog line that I was told that I could only order online. They arrived as a pack of two and will last me ages now that Milo is behaving!!
