He looks very young, and thats pretty common for a new dog. getting used to you.
When i got my dog he was about a year old but he acted absolutey nuts for the first few weeks and really levled out after a few months and is docile and calm now.
Just to give you an idea how bad he was>couldnt leave him alone for more than 10 minutes or he would start tearing everything up starting with the trash can.(he will tear some stuff up but only when im gone for a week or two and i leave him with the family).>He wouldnt come in my room if i had the light off.>he would pee himself from being excited >he wouldnt sleep in my room
and just normal stuff like that.
they grow out of it.
