NOT a first time dog.
They require a strong leader and are stubborn. They are independent for the most part, they ca be a bit shy, or even aggressive with strangers unless they've grown up with the right household.
They were bred for flushing game, and are highly trainable.
They are very tough, they could walk for hours in the snow and still be ready to go.
They do not do well if left alone for hours at a time, they need pack structure, and as intelligent as they are, they can wreck a house if they get bored.
Socialization if NEEDED as a puppy. If they are not socialized with cats, dogs, people and small children fro ma young age, it could cause problems.
They have a high prey drive, and can not be trusted around small birds, rats, ect. or their instincts may take over.
I have had bad experiences with a shiba X GSD mix who's in the wrong hands. He is a menace and ought to be put down or wear a muzzle everywhere, because his owner will not train him. Me, my family and our dog have paid for his negligence and lax in training. I watched this man and his dog yesterday, a friend of mine was walking with his rottie and basset mix, he also had his tiny ids with him, when they saw the man and his dog coming, they went off to the side(there was a seawall preventing them from moving more) the avoid him. But the man just allowed his dog to get close enough to them that I'm not sure if it did manage to bite his dogs.
They are strong-willed, stubborn, vivacious dogs, but make excellent pets in the right hands.
this is good reading for a potential shiba owner:
