Dogs dig for several different reasons. Sometimes dogs dig to make a cool spot to lay in the hot summer. Or they may dig to try to escape from the yard so that they can go on a tour of the neighborhood or meet favorite friends. Occasionally dogs with separation anxiety dig out of their yard in an attempt to be reunited with their owner. Some dogs dig to pursue the odor of prey animals. Others dig for fun or buried food. Digging may even be an expression of the obsessive-compulsive behavior (e.g. a component of shadow chasing).
It is not always easy to determine why a dog is digging. Some breeds are predisposed to digging. Terriers and dachshunds, for instance, have been bred to dig in order to get into animal dens underground. Dogs with high energy levels may also be prone to dig as a way of channeling their excess energy.The positive impact digging may have in a dog’s life is that it serves as an energy outlet. However, the negative impact digging can be a high level of aggravation for the dog’s owner as the yard begins to resemble a minefield. In addition, digging (“excavating”) brings with it the very real risk of the dog escaping from the yard and getting lost, hurt or even killed
The very best way I have found to stop dogs from digging is to take them for long walks and get them exercise. Walking is a necessity for your dog, and it’s a myth that dogs who have a yard do not need to go for a walk. Walking provides exercise, bonding time with the owner, communication with other dogs and people and, most important, walking also provides dogs with a chance to explore.
Good luck with stopping your dog from digging, and remember that is the key to correcting any dog behavioral problems. If your dog respects and trusts you, he will be eager to please you in all situations.
