Sometimes it takes a few days for them to recover from shots. My 2 only get 1 vaccine at a time because it takes so much longer for them to bounce back. Also you should really teach your children not to bother her (or any dog) at all when she's sleeping or eating. That being said I would firmly tell her "no" when she growls or snaps. You might want to let the vet know about this because it sounds like it's a reaction to the shots.
