Hi, I posted on the main forum. Mouse has been on Caninsulin/vetsulin for past ten days, 1.5 u twice daily. I am switching him to Prozinc and he is due to get his first dose tonight. The vet said to leave a 24 hr gap between Caninsulin and starting Prozinc so I have done that. She said to give him 1.5 units ProZinc, which is higher than the starting dose recommended in ProZinc protocol, so maybe i should just give 1 unit? His fasting numbers have been high, 27 mmol, and 19 mmol 3+ and 5+ caninsulin. Am going to try to do the spreadsheet!
