The vet diagnosed BJ ( FIV positive and survived heart worms after his rescue) with probable lymphoma. One kidney enlarged. Kidney values very high. This appeared immediately after a respiratory infection, an ear infection and then dental extraction of all teeth but two. He is active. After rounds of fluids, antibiotics, acid blocker and anti nausea he was well enough to come home. He urinated at vet and had BM. He had one day here where he ate well , drank water and seemed in pretty good shape. Much better. Came home on Sub Q fluids, acid blocker, anti nausea and was to start prednisone. This morning he was throwing up white foam and after anti nausea pill he drooled extensively. Back to the vet. Ultrasound shows the same with kidneys but vet says fluid around the enlarged kidney. Slightly low body temp. Active and alert but not feeling as well and did not eat today. Vet suggested euthanasia. I asked about UTI, blockage, constipation and ears. Ears were showing infection again and some redness. I had them put him on all meds via IV and keep him overnight. I want our usual vet to check him and explore other possible issues. Any suggestions welcome! Any input on fluid around kidney???? Hoping.
