been through this a few times over the years and it is not easy to carry out but it is your duty to your beloved pet.
like many have said above, go into the room and snuggle and love them as they get the shots. your pets are only a part of your life, but to your pets you are 100% their life.
after the process is over, grieve but only briefly for a life well lived and then get another one. do not fall prey to the position of "i can't get another one because they will die someday too". give of yourself to another dog and make their life a part of yours.
good luck
