go with the smaller dose, there is a margin of error, and the larger size could be too much,

My smallest dog is a border collie that is approximately two pounds less than the K9 Advantix II for 25-55 pounds, but she has taken that treatment well, so I would guess if you gave your Yorkie the treatment for 11 pounds it would be OK. However, since smaller dogs proportionately can have the most difficult side effects, I would only give her half a tube, and watch for reactions the first time, just to be safe. If no negative side effects then complete treatment, or if fleas are stopped with smaller dosage, then you've accomplished your goal.
