I would assume its normal, maybe he senses something about the house. When we first got our pup I worked in the country and took him on daily walks to the busstop but when I would walk him around my house in the city he would get skiddish. There were two beagle pups in a yard barking at him and he refused to go even near the sidewalk of the house, slowly he got over it but it got to the point where we had to walk on the other side of the road til we passed the house and then we were fine. Not exactly sure what it is.
