In what general area are you located? Have your vets investigated tick borne disease? Fever and an enlarged spleen point in that direction. Unless the vet can come up with something else quickly, I would have them put your dog on Doxycycline (antibiotic) at the dosage below.

"There are four major tick borne diseases that affect the dog in the United States: Ehrlichiosis, Babesiosis, Rocky Mountain Spotted Fever and Lyme Disease.
All, with the usual exception of Lyme disease, may be fatal unless diagnosed in time and treated aggressively. If you cannot get a firm diagnosis and nothing you do seems to help; if you cannot and will not settle for anything as vague as "compromised immune system"; if the symptoms you see make no sense and/or the treatment your dog is given does no good, you should consider the possibility that your dog has tick disease. Sites listed farther down the page are highly recommended to help you learn about and combat it.
Important! Here is the treatment your dog should be given for Ehrlichiosis or Lyme disease. Doxycycline, a semi-synthetic tetracycline, is the drug of choice, the most effective against Ehrlichiosis and Lyme. It is given at 10 milligrams per kilogram (1 kg = 2.2 lbs.) of the dog's body weight every twelve hours for six to eight weeks. Another way to figure this, on the basis of pounds, is 5 mg. per pound of body weight. The result for the dog is exactly the same as doxy comes in 100 mg. tabs and the result of figuring in milligrams is usually adjusted up accordingly. If nausea is a problem, you can divide the dose further, as long as the dog gets what he needs in any twelve hour period.
This is twice the amount recommended in the Merck Veterinary Manual and is given for a longer period of time than the VMM recommends; however, vets who deal with tick disease all the time say that the higher doses and longer administration are successful far more often in treating this disease and preventing its recurrence.
Doxy is not used to treat Babesiosis and has little to no effect on it.
Dogs with Lyme disease that cannot tolerate doxycycline may be treated with amoxicillin as an alternative; it has no effect on Ehrlichiosis. I have read reports of IV Rocephin being used to save dogs in extremely bad cases of neurological Lyme. ...
Ehrlichiosis is more than E. canis. Way too few vets seem to know much about tick-borne disease, fewer seem to realize that a dog that tests free of E. canis on the popular Snap test for heartworm, E. canis and Lyme, may still have another strain of it or another form of TBD altogether. (Some are resistant to even considering testing for tick disease and if you run up on one of these, don't let the door hit you on the way out! Go find a vet who will.)
If it's not E. canis, it could be equi, platys (a form that attacks the red blood cells), ewingii or risticii, though there are others, some unnamed. And, worse luck, cross infections with more than one type of TBD are common."

"Ehrlichia can only be treated by doxycycline or other tetracycline antibiotics, which are common medications that also treat Lyme Disease and other tick-borne illnesses. ...
Ehrlichiosis may cause any (or none) of the following symptoms: weakness; lethargy; cough; fatigue; pneumonia; intermittent fever; arthritis; muscle wasting; slightly increased urine alkalinity; mild reactions to vaccinations; low red blood cell, low white blood cell, and/or low platelet count; discharge from nose or eyes; reflective, glassy eye appearance; retinal hemorrhages; red eyes; depression; loss of appetite; increased thirst and urination; head tremors; disorientation; seizures; neck or back pain; bleeding; anemia; bleeding into the skin; rash; nose bleeds; spontaneous bleeding; abdominal tenderness; swelling of the legs; swollen lymph nodes; enlarged liver; enlarged spleen."
