Hi all! It's been several months since I have posted. I probably should have requested advice more often, but life has been a bit crazy. I feel kind of guilty to be honest. Charleston has been consistently getting his dose decreased. He's down to .25U right now. He also lost another pound and is now at his ideal weight per the vet. I've been slowly getting comfortable shooting lower and lower numbers. In the beginning I wouldn't give him insulin if he was less than 300 (my vet's number), and now we've worked our way down to 150 as his no shoot number. He's been below that at almost every shot time for the last week or two, which means lots of skipped doses. He got blood and urine testing done last week and everything looks good - no glucose or ketones in his urine. No ketones from my home testing either. My vet has access to my spreadsheet, but hasn't given very clear guidance on what to do at this point other than "keep doing what you're doing." It doesn't seem to me like he's ready to come off insulin completely, but I'm trying to figure out what to do next. I've been using SLGS, but thinking maybe I should switch to one of the alternative Prozinc dosing methods? I work from home, so can pay very close attention to his BG. Or maybe he should get an even smaller dose than .25U? Any advice is appreciated. One other thing worth noting - he's got a mast cell tumor on his ear and is going in for surgery on Wednesday to have it removed. He'll be getting his teeth cleaned as well. We're not sure if the tumor is cancerous yet, but will find out after a biopsy. Poor dude is having a rough year health wise. Thank you!
