Although intelligent little dogs, the Cairn Terrier can be stubborn at times thanks to their quite independent natures. Their training needs to start as early as possible and they need to be handled with a firm, yet gentle hand from a young age so they learn all the ground rules. Once a puppy has been fully vaccinated, it's a good idea to enrol them into an obedience class which would pay dividends later on with the added bonus being that Cairn Terriers really enjoy taking part in these classes.
