My old dog, who frankly was the most placid chap ever, was always sedated for x-ray - I really don't know why because he would've let you chop his leg off without doing anything, but I just figured that was standard stuff really!

I don't know if anyone knows of any other reason the PH would be at 8.0 other than a bacterial infection? That seems to be the only "constant" with the urine. INcidentally, I asked the vet if they'd done a USG reading in either urinalysis, as my understanding is that the urine specific gravity reading is quite significant in diagnosign diabetic insipidus, but apparently they didnt' do USG readings......

Hmmm...........

Thanks guys. Will see how he gets on. My 2nd culprit would also be the anatomical deformity. The only thing is that he's fine whilst asleep, which you'd figure he'd be worse if he was asleep if it was something physical rather than a disease, if you know what I mean?
