Hi
I'm not sure what the specific symptoms are, but you should watch for any swelling of the face/head with any immunizations. Also, refusing food, vomiting, runny stool and lethargy. Now sometimes pups will feel a little icky for the rest of the day after their shots, but it shouldn't be extreme and it should not last more than a few hours. As long as she's eating, playing, and pee/pooping, all should be well
Hopefully someone with some actual knowledge of this will come along shortly
