A Shiba Inu tends to take ownership as soon as he is introduced to a new environment such as new home after being brought from shelter. Major concerns should be dealt with as soon as possible, preferably when the Shiba Inu is a puppy. The Shiba Inu is a busy body and an owner must pay close consistent attention to him in the first months of training.
Shiba Inus are similar to cats in that, when they become angry or are just restless, they will chew and rip the sofas, or dig up holes back yards. Obedience classes that feature lots activities can be outlets for built up aggression and/or energy. When the Shiba Inu try to claw and bite at its owner, a safe disciplining technique includes using a squirt gun or breath freshener spray on hit to teach him not to misbehave. Also it is important to try and exercise your Shiba Inu everyday by walking and playing with him.
A Shiba Inu is quite cautious around strangers. They have an instinctive trait to always be on the defensive with people they do not know. It is important to expose your Shiba Inu to as many different places and people as possible to get him acquainted and familiar with the places you might have to take him regularly. If there are children present in a home, in the Shiba Inu might not be the breed of dog to invest in as children might trigger his defensiveness. It is a good idea to always supervise children with a pet Shiba Inu.
Shiba Inus are also quite possessive with what he perceives to be his property. This is an offshoot of the defensiveness he naturally feels. A way to break that wall down some is by, holding onto his food bowl or water bowl while he eats and/or drinks from it. When he does not react negatively to you doing that, reward him.
Because of the strong independent spirit of a Shiba Inu, he can sometimes be stubborn. What a Shiba Inu owner has to do is be constant and consistent on discipline and teaching moments. It may take a while and lots of patience, but it will be well worth it. The defensiveness and of a Shiba Inu can translate into fierce loyalty and constant love for you and your family
And finally a fence is a must. The curiosity of a Shiba Inu will send him over fences that it would seem impossible for him to get out. Make sure that the fence is as high as allowed in your neighborhood and ensure that the locks are good, solid ones. Also, look for holes dug near and under fences, because Shiba Inus are always looking for a way to go and fill their curiosity about the outside.
