In the first weeks we had our dog, my husband moved his dog bed and our dog low-growled at him. Anyway your dog might also feel like the places where lays (sofa, kennel) and his toys are HIS and gets upset when your wife messes with them...
We fixed our issue by having husband walk him, feed him, and play with him. ( I figured it was mostly a trust issue, since I was always allowed to move his bed, change blankets, pick up toys and even thump his Kong out, and he would just look on calmly.)
While you are working on his solid training, one easy workaround would be to do the tidying while he is out for a walk, or out in backyard?
