You obviously haven't read the link, you obviously haven't had a GSD suffer from CDRM which amongst other things is a strong link to vaccinations, I shall tell you a story, I had an attack of gout, the quack had my blood analyzed and it came back 6.5 uric acid level, he assured me that 3 was the upper limit, then said my BP was high, more pills, my ankles swelled up and I thought enough is enough, I googled uric acid levels, for women the upper level is 3, men however the upper level is 7. I promptly binned all my pills and now feel much better for it, BP can be regulated with beetroot juice, I had a few days on plums which are a diuretic and my ankles were back to normal, my GP drives a big Merc, read between the lines.
