Ok, Ian has had his ultrasound today and the good news is that there
is no 'obvious' sign of a tumor. Although the vet STILL doesn't rule
it out???

He has had a sample of the fluid taken from his distended abdomen and
it is a 'yellow fluid' that is being analysed. It will take a couple
of days to get the results back. In the meantime I am to take Ian back
home tonight (even though he still has the fluid distention and will
be unwell).

The vet doesn't seem to have a clue as to what might be causing it. He
has had bloods and they don't show anything like an infection, his
temperature is ok etc. His major organs 'seem' ok apparently.

So its just awaiting the result of the fluids now.

Does anyone have any clue as to what might be going on? What the fluid
might be? The vet still seems to imply its probably quite
serious...what is he trying to tell me?

I'm so upset :-(
