Forgot to mention - girlfriend getting better and the dog now eating, drinking and just about walking around on its own, although with quite a stagger, which is a remarkable recovery from being a mere whim from being put to sleep with the girlfriend's blessing (it is actually her dog) on Tuesday when nothing seemed to work. It can even jump into the armchair now. I have always been sceptical of some of the medical profession and find this is another example of how they often go for the easiest diagnosis.( I can forgive some for being overworked.) As with investing, the internet opens up opportunities for careful research to pay dividends, and I recommend anyone to double check what they are being told. Medical patient forums, even veterinary, are a fantastic source of information.
