Poor Munchkin

Munchkin (our 9 month old Miniature Schnauzer) is not herself. She could barely get around yesterday. It's as if she's in a daze. Then I remembered she was vaccinated on Saturday. Could she be having a reaction to the vaccine? Why do I vaccinate my dog when I don't vaccinate my children? I did think about it prior to getting it done, but I've heard such nasty stories about rabies, parvo, and distemper. She's feeling so rotten, she's not even barking:(
