Do you get these for her yearly? If so, you may want to consider going every other year, every three years, or even better - titering. The titers would tell if her immunity was low (usually a dog is fine for a long time, even a lifetime, from one series of shots). If that's not something you want to do, try going with individual shots and spacing them out by a week or more.

Shot reactions can be very serious. I'm glad Rita's feeling better though
