When left alone without any amusement, beagles will find their own means of passing the time. Often this is digging. If you have a prize garden, the beagle needs to know the rules of where they are allowed to go and will need company to keep their mind elsewhere. Because beagles have an excellent sense of smell, they will often smell out worms or lawn grubs that are in the soil. They may try to dig for the lawn grubs. If they are left alone and have a need to get out of your yard, they will become very resourceful, including trying to dig under a fence.
