I'm in Canada and need to start our Zorro on B12. He's got neuropathy in his hind quarters which seems to be getting worse by the day. I've picked up some SISU B12 (see attached) but need some advice on how much to give him and how often. The pills are 1000 mcg's each and the dosage for humans is one pill a day. Our vet was unaware of the difference between the methyl and cyano B12's and I can't wait while he tries to get answers from his specialist contact (in Australia). Zorro is unregulated and we are trying our hardest to regulate him but need to give him the B12 in the hopes it starts to help with the neuropathy. Thoughts anyone?
