I think you moved too fast by taking away the bone and maybe you overreacted in his opinion (due to being worried). I can see his point.
He only did this in the dining room when he was near or under the table. I think he thinks that the diningroom table is his den and I went in there and took his stuff. I will give your suggestion a try. Thank you
