GP been losing blood from rear end, been to vets who said could be infection, stones, or tumour. Been on antibiotics for a week and seemed to clear up, however since stopping antib has come back. Vets now want to do further investigation, Xray etc. Now Im a GP owner by default, as I took in to help someone out so not that up on them, but believe they can just go downhill quickly if ill. APart from the cost, would you go down the xray poss. surgery route for such a small animal ?
