I'm sorry about that. Most of my reply seems to be missing, and I'm not sure what happened to the begining of it. Here it is again:
A fever is a method of fighting infection, since most bacteria and viruses don't thrive in hot environments. Possible causes of fever are infection, inflamation, cancer, drug related symptoms, immune system disease, or idiopathic (unknown).
Having a fever is different from hyperthermia, which is an increase in body temperature due to external influences. Hyperthermia is treated by placing the dog in or dousing with cold water.
Your dog's normal temperature is 101.5F. For mild fevers of less then 104.5, taking care of your dog at home may result in spontaneous recovery.
Make sure your dog continues to eat and drink, and take your dog's temperature 1-2 times daily. If your dog's temperature goes above 104.5F, call your vet.
Examine your dog for any areas of infection such as abscesses, lumps, blood in the urine, straining to urinate, and upper respiratory symptoms. If your dog is lethargic or has a lack of appetite, you should contact your vet.
You can give your dog non-steroidal anti-inflammatory agents (NSAIAs)to help bring his fever down. These drugs treat both pain and fever.
You can try Ibruprofen, at a dose of 6 mg/pound. Because these drugs can irritate the stomach lining of dogs (usually when taken over a period of 2-4 weeks), it's recommend that they be given with medications that limit stomach acidity, such as cimedetine(Tagamet) or ranitidine(Zantac).
If your dog's fever persists or rises above 104.5, you'll need to take him to the vet. Ketoprofen is commonly used to treat a high fever. Commonly prescribed antibiotics to treat the cause of the fever are:
If antibiotic treatment is not effective, additional testing will be needed.
