ADOPTED BOSTON SCARED OF EVERYTHING

(SOCAL )

Here is my story I just adopted a one and a half year old male Boston. The boston was picked up from a family that had two bostons and had to downsize. When I was introduced to the boston he was rather nervous but did let me pet him and even licked my hand. I took him home ( this was 2 nights ago ) and he seems very scared of everything to the point of trembling in his new enviroment. He has not eaten or drank any water however If I put some food in my hand he will eat and if I dip my hand in water he will lick it. He tenses up if I try to pet him or pick him up which I tend not to so he can adapt on his own. He has not showed any aggression and in some occassions if i get close will lick my hand or arm. He pretty much stays in my bedroom in his crate ( He has been crate trained ). I also noticed he seems to be licking his face alot and wonder if that has something to do with his anxiety. I have managed to take him for walks which he actually likes and after getting home follows me around for a bit then recites right back to his scared ways. Is there any steps I can take to help ease his fear to our family? I live with my 7yr old daughter and wife and it's the same with them also. We also have a sh1tzsu also which we have not introduced to the boston yet. I'm really starting to feel our new addition is not happy with us even though it's ony been two nights thus far. Am I getting ahead of myself here or shall time heal his anxiety and he will come around? Please give me some feedback on this and thanks in advance.

Here is a picture of our new addition to the family ( anyone can also shed some light on why some bostons have that lower underbite )
