They do not typically jump high fences or dig. Because of their personalities, (like swimming, playing, running, sleeping, and eating) some Labs climb and/or jump for their own amusement. As a breed they are highly intelligent and capable of intense single-mindedness and focus if motivated or their interest is caught. Therefore, with the right conditions and stimuli, a bored Labrador could "turn into an escape artist par excellence".
Labradors as a breed are curious, exploratory and love company, following both people and interesting scents for food, attention and novelty value. In this way, they can often "vanish" or otherwise become separated from their owners with little fanfare. They are also popular dogs if found, and at times may be stolen. Because of this a number of dog clubs and rescue organisations (including the UK's Kennel Club) consider it good practice that Labradors be microchipped, with the owner's name and address also on their collar and tags.
