Hi this is dRB and I would be happy to help you with this......I am sorry that you are having all this trouble.....so there are several types of things that need to be ruled out.......infectious diseases, inflammatory diseases....let me list some of the rule outs for you so that you can talk with your vet: Infectious diseases that could cause these symptoms are as follows: lyme disease, anaplasmosis, ehrlichiosis, chronic RMSF, bartonellosis,leishmania,and babesiosis. (And there are other possible infectious diseases as well but these are the big ones)
Then we have to rule out inflammatory diseases which include different forms of cancer and also various autoimmune diseases.........lupus is certainly oneof the autoimmune diseases which need to be tested for.
So, you need the following testing: CBC, chem panel, lyte panel,4dx, urinalysis,Tick panel serology and PCR ,ANA test, chest radiographs, abdominal ultrasound.
I hope this helps you but please let me know if you need additional help. Sincerely, DRB
