If you're looking for a guard dog that doubles as a nanny, an Akita may be the perfect pet for you. This large breed has strong protective instincts and will immediately investigate any hint of an intrusion into his family home. But unlike most other dogs, the Akita usually investigates quietly. If it barks, that probably means something is seriously wrong.
The potential downside of owning an Akita is that this breed tends to be quite independent, which isn't always a good thing for a large dog with strong protective instincts. Akitas need to be trained and socialized early and continually throughout their lives. When considering an Akita or any potential guard dog, ask yourself how much you're willing to work with the animal. Your canine companion will need to be under your control if it's going to function as a guard dog. That will undoubtedly require a bit of skill and dedication on your part.
Assuming your family has time to devote positive reinforcement and encouragement to your Akita, this breed makes an excellent guard dog and loyal family friend. It would be virtually impossible to harm a member of an Akita's family while this animal is around.
