I need any information anyone has on fevers of unknown origins with dogs, especially Weims. My Weim will get a fever of about 104 to 105. I rush her to the vet, they give her fluids, metcam, anti-biotics, and a course of anti-biotics for home. The fever goes down for about a month, and then all of a sudden it comes back. This has repeated itself about six times now. The most recent being last night. She has had every test they can think of with no abnormal results. Even rocky mountain spotted tick and she has never left the state. I can not afford to take her to MSU until at least October. Thanks and I will respond to any posts after I get home from work today at five or so.
