Sealyham Terriers possess a unique combination of independence and intelligence.

Training should be positive and reward-based, as Sealyhams respond well to praise and treats. Consistency and patience are key when it comes to training these terriers, as they can be stubborn at times. With a firm yet gentle approach, they can learn commands and basic obedience skills. Engaging in regular training sessions and providing mental stimulation through interactive games and puzzles will keep their intelligent minds sharp and satisfied.
