I often sit on my terrace and work at my computer. This gives my dog Iji (which means dog in Tamachek) the opportunity to bother me. He loves to be petted and as I am the only one to do this he fully understands that if he puts his head between my hand and the keyboard he will not fail to get attention. It certainly stops all progress typing. He does manage to open some interesting windows with his nose–not sure how he finds them.
