I need to take Khorra in for her third set of shots this week. I'm wondering if I need to have her wormed again. The first time I took her in they tested her and even though it came back negative, they gave her the worming medicine anyways. I was fine with that. The second time she went in for shots they tested and wormed her again without telling me and said that it was routine. Well, should I let them go ahead and test and worm her a third time or should I just tell them no? If she doesn't need it, I don't want to spend the extra money.
