Hi There
My 4 year old Springer can sometimes be like that, he is just showing he is submissive. the best thing is to give him fuss on his terms as he is a little nervy, don't make a fuss as you come in the house, let him settle and come to you as they can get overwhelmed with all the excitement.

Good Luck
