Marou is quite the mischevious one, as he will get into just about anything and try to play it off as if he didn't know we were watching him the whole time. In addition to the typical "Mine!" attitude of the Shiba, he seems to think that he can just get into whatever he wants then look cute when he gets caught and everything will be fine. He's quite the spoiled little Shiba, but his exploration does provide Josie and I with some high quality entertainment.
Exploration of new things or changes is perfectly fine and honestly quite entertaining as long as you make sure to pay close attention to your pup while he/she does it. Satisfying these natural curiosities is part of what helps make our dogs better adults and better behaved canine citizens overall. Keeping you pup out of mischief while he/she is exploring is priority number one, as this is the best and simplest way to keep your pup safe and sound.
Luckily, the closest thing to mischief that Marou gets into is try to run toward the neighbors who are terribly afraid of dogs and trying to play with every animal he sees (including strays). He loves to try to explore at night, but all that happens is that he gets startled by every little leaf that he steps on and every little thing that moves. He's a little scaredy-dog, or as a friend of mine would say, "His bark is worse than his bite."
