I have only had little Jill for about two weeks now when I had to take her for her distemper booster. I later found out that this booster actually has like 5 things in it. Anyway, She was a perfect little angel at the vet, except she threw up. (She gets car sick. I hope she outgrows that!) After she got her injection, she seemed fine. I had to be a work very shortly, but something told me not to leave her. I waited for my husband to get home. When I left for work, she was fine. About 2 hours later my husband called and said she was acting funny. Crying when he picked her up like she was in pain, not wanting to lay down, and she was wobbly. I told him to call the vet. They said it didn't sound like anything but he could bring her in if her wanted to. Well he did! When he got there they took her back without him and gave her a shot of prednesone. Now she has to have that before the next booster, in three more weeks. when I got home, she looked terrible, I though she was going to die, she is so little. Only 2 pounds and 12 weeks old. When I asked them about a reaction they said that it would happen right away. well it didn't. It took about 5 hours for her to get back to her old self after that prednesone. Thank goodness we didn't leave her alone at all. I don't know what I would have done if something happened to her. I will post some pics when I can. Thanks for listening.
