Thank god its normal behaviour, lol.
I'm VERY scared that anything bad is going to happen to him, I'm actually paranoid, to the point that he's never ran around my house without a leash on.
I gave him a chance in my room, unleashed and he goes potty

He doesn't seem to be too interested in wires, i don't know if thats the case when he is bored.
We have a Kong toy (free, from vet) annd he absolutely hates it

He hates rubber toys, loves stuffed animals and ..sqeaky things, ropes are fine too.
The penny can doesn't work, he gets scared and barks even louder
How long do u think I can let him roam around my house on his own? What about sleeping time? He sleeps in a small kennel, with comfy pillows and doors closed, in case he comes out during the night and goes potty on the carpet. He can last through the whole night without going, I don't know if he can hold it if he doesn't HAVE to.
Thanks in advance
