Just got back from a vet visit with Ellie to go through her blood test results. And she is negative on everything! The only value that was abnormal was sugar, and it was extremely low. I am of course very pleased, as I was thinking the worst, but it leaves the question of why she is so thin and has been losing weight. The vet wants me to try her on a high protein diet for two weeks, and he has ordered some extra rich Royal Canin wet food that I cannot get in the shops. I will pick it up tomorrow. So I am 200 euros lighter, very relieved and still worried at the same time.
