I have a large number of border collies that over the years have frustrated me with their nuisance barking. One of my collies loves to bark at almost anything. At times his barking would set off some of the other dogs and the worst part was it was mostly of a nighttime, so I bought a Sportdog bark control collar. I couldn't believe how quickly and effectively it controlled his barking problem, so I used it on the other barkers and it worked a treat. A few years and a number of bark control collars later, my dogs still bark every now and then but constant nuisance dog barking isn't a problem anymore.
The collars are great on Neo Mastiffs. I have experienced instant results. Complete bark control for big dogs.
This dog trainer is great for young & old dogs. It's really easy to use and it has plenty of range. My dog was driving me mad with his disobedience in the field, now I am back in command & can control my dogs behaviour from greater distances. I can discourage him really quickly and teach him whats acceptable and whats not. It's a great tool, now I always get my dogs attention when I need to. I wish I had one years ago!
