My Dog Hates My Laptop

More specifically, my dog hates when I'm working. As soon as I sit down to write, he barks, whines to go out, and makes a nuisance of himself. I've tried to ignore him, pay him a little attention, give him water / food / toys, and then go back to typing, but it seems that he's just not satisfied until I'm on the couch with him next to me. If I am doing other things around the house, he leaves me to it without complaint. My sitting at a desk or table, focused on a screen, however, angers him. At least, that's my excuse this week.
