As you all may well know, Barney has been suffering on and off with cystitis for about a year now

We have seen 2 other vets, who, without any tests, have diagnosed 'stress', whilst I am not dismissing their diagnosis, I am determined to make sure there is nothing else going on with his bladder, as my old vet is now back from having a hip operation, I am taking him to see him tonight, as I know that he will insist on tests before concluding that 'stress' is the issue.
Just wondered if Barney would need to be put to sleep for this procedure or if there would be any other tests he may need ? I just know that if he had to stay overnight, this would stress him out to the max in any case, though I know it is for the best.
Any advice gratefully received !
PS: He has been ok the last few days too, just before the vets trip !!!
