Thank you guys. That reassures me a lot.
I hope he will grow out of this. Any other advice or stories about your own puppies would be very appreciated.
I'm just wondering if I should be keeping him at my side or in the same room most of the time OR should I be training him to be comfortable alone as I have been trying with him crying away from me?
At what point could I leave him for longer periods and for how long? He's only 13 and half weeks old. I'm a man and I've been walking around with him in a bag a lot hahaha. But I'm fine with this at least for now.
I just don't want to cause him long term trauma...the crying is pretty hard. Also I'm afraid my neighbors will start complaining when I eventually have to leave him for longer as he grows. i'm in a very dense apartment.!
