Hi Guest, I can tell you that your dog will require Vivitonin for the rest of it's life. This is a prescrition only drug, so you are unlikely to find anyone to sell you any great amount of the stuff. You might find someone who's dog has died and they have a little left over, but in the end you'll have to aquire it from a legitimate source. Please don't be tempted to reduce your dogs dose, it will only result in the recurrence of it's symptoms. I tried that once and it was not worth it.
