<My dog in on Vivitonin, because he had a stroke and it is to improve the blood flow or so I am told, know of one person who gives their older dogs it as a mater of course.>
Yep, same here. Charlie was put on vivitonin about 2 1/2 years ago when he had a stroke, to improve blood flow. He's been on it ever since and is now approaching 16, so I have no intention of stopping it to find out if it helps or not.
