Personality
Border Collies are always ready to work, attentive, lively, and alert. They will form a very close bond with their owner and family but, unless given plenty of time and exercise, they are not ideal pets for a family with very young children, as it’s in their nature to herd anything that moves - your children included! If not kept physically and mentally stimulated they will become bored, develop behavioural problems or get into mischief, as their brains are always active.
The Border Collie will suit an extremely active owner who is able to give them plenty of exercises, enjoys training, and wants a very full-on dog.
