Many times when people get a Kerry Blue Terrier, they are not sure of how they are or will be with other animals. However, the way they act is usually seen by the way they are raised. Although many times it is seen in their bloodlines, as well.
As many people raise their Kerry Blue Terrier they are always hopeful that he/she will grow up to be a great disciplined dog. However, for some people that is not possible. In fact, many people have problems with their dog getting along with other dogs or animals. In fact, the Kerry Blue Terrier is known to be very head strong as well as high spirited; however, they are also can be down right mean. In some cases, the Kerry Blue Terrier has even killed other animals. In fact, in the earlier years, while the Kerry Blue Terrier was in competitive dog shows they were required to pass certain "game" tests; which were known as the Teastas Mor. Before they were passed for that certification they were expected to catch rabbits or to be able to bring a badger to bay. Back then and even today, their nicknames are the "Blue Devils".
Because the Kerry Blue Terrier is very aggressive towards other animals, they are not possibly the best animal as a pet. In fact, many times they will even go after other small pets such as a hamster or cat. However, many breeders are attempting to breed out the aggression; for the most part they are successful. But a lot of times the aggression stays with them because they are not socialized enough when they are/were puppies; which is an absolute must. Not only should the puppies be socialized when they are at a young age, but they should go through a series of obedience classes as well. In fact, it is very important to show your Kerry Blue Terrier who is the boss right from the start. You should also remember to never give into them otherwise they will think they are the boss and they can do whatever they want. If you are not consistent with your terrier, he will try being the boss of you as well as everything else; which would be your mistake.
Even though is it known that the Kerry Blue Terrier is not a fan of other animals, it is possible for them to live in the same household with others. In fact, in many cases when they are in fights they are not the one that started the fights; they were the one that ended it. Kerry Blue Terriers are not dogs that can walk away from a fight. However, if you are planning on having your dog into a family environment you will have to properly introduce them into the situation.
Whether you are planning on getting a Kerry Blue Terrier or not, you should not let the history of them be a factor of your decision. You should get the dog solely based on the decision of if you want that type of breed. If trained at the proper age, you should have no problems.
