Early socialisation to other dogs, children and livestock is essential but even then, they are unlikely to mix well with cats - and may even consider resident cats as prey outside the comfort of the house or if their predatory instincts are aroused. A well socialised and habituated Kerry Blue is easily capable of many canine sports and activities, but they are not a dog to ignore a challenge or perceived threat and owners should always remain aware of their game, feisty nature. When it comes to dog training, they respond well to positive reinforcement and are quick learners once they believe that what you want from them was their idea in the first place!
