Border Collies bark a lot, and this is something all dog owners need to learn how to deal with. The thing with these dogs is that they were bred to be herding dogs - so, this means they are extremely vocal dogs, and will inform their owners of any potential danger. But, this might get annoying, since these dogs will usually bark at every little sound or movement. If your Border Collie doesn’t get enough exercise or it lacks mental stimulation, it might bark even more. Also, these dogs tend to suffer from separation anxiety when they spend too much time away from their owners. This might also cause their barking to get even worse. Border Collies will often bark out of fear, or, unfortunately, due to health problems. And, let’s not forget one of the most common reasons for this dog’s barking - strangers! Dog training and early socialization are crucial in controlling Border’s Collie barking. In some extreme cases, dog owners even have to ask help from professional dog trainers.
