Worried about my pup

Sa

So most of the time, my 2 year old terrier mix acts completely normal. He is still playful, eating normally, all that. However, he used to run up to our bedroom and jump on our bed whenever we called him. He loved being on our bed with us. Recently, if I try to call him upstairs, he either runs the other way or hides in his crate. He doesn’t have a problem with stairs, he goes up and down them whenever he wants to. He just seems almost scared of coming to our bed anymore. If I carry him upstairs, as soon as I get to the room, he wants to be on the bed. Once he’s up there, he will lay with us no problem. We just sold our house and have started packing some things (nothing of his yet), so I don’t know if it’s just that he is confused and worried about the change. This is the only house he has ever known. Should I be worried about it? I don’t want to be overly concerned because he has been eating fine and still very playful and energetic. I don’t think he is sick or anything.
