ok - I'm back and have had a look at the spreadsheet. I am quite surprised at the advice given by your vet, as the start dose looks high (not to mention giving Caninsulin once daily) and I think the dose is still too high.
Has Murinka ever had ketones?
Do you know what the sugar level was at diagnosis?
How much does Murinka weigh?
Do you know what her ideal weight should be?
It may be best to start again with the dosing but if you can answer the questions I can have a think about what the best way to deal with this would be. I see the +2 was 7 so she is in nice safe numbers. What has happened with the high doses is she has been going too low then bouncing up again so we need to give her a little rest such that she gets blue mid cycle numbers from a good safe start point, it may take a little while to find her ideal dose but it is better to start low with the insulin dose then slowly raise it. It looks as though her dose was too high from the start.
Can you answer the questions and then I can try to make a suggestion with where to go from here.
Yes, it was way too hight - I know it now, but I had no clue back then

- the vet is I think more experienced with dogs where as far as I understood Caninsulin can be taken once a day ... after reading stuff here I came to a conclusion that her dose is a nonsense - too hight and once a daily and we agreed with the vet to split in 2 per day. First he said 4units morning and evening but she was slighty hypo and I had once decreased her PM dose, then he decreased her dose to 3units 2xday. But today she only had her morning shot of 3 units and was in good numbers even after 12 hours after the shot!? Why? When at the begining with 7 units in the morning she had above 20 in the evening. This makes me desperate
But to your questions:
- I don´t think anything about ketones and don´t think she´s been tested and the vet never said anything about ketones - he only took her blood
- I think she was at 25,8 but not sure - I have the report from the at home and Im out off the town now and back tomorrow and I will complete the spreadsheet with numbers from the first day she was diagnosed - but basically AM she was around from 18 to 25 and the evening the same.
- when she was diagnosed her weight was 5,7 kg - she lost around 3 kg before we figured out something was wrong. she was overweight for ages (8,7 kg) despite our effors end her diet (she´s been on Hills Prescription R/D - I know now that this was not good for her, but again, back then I had no clue, that this kind of dry food is terrible and not appropriate at all ...).
- her ideal weight actually should be around 5.5 kg. But I think she might have lost a bit, because I took her for vacation with me and here she´s moving much more than at home so she might have lost a little bit, but I can´t weight her here.
I spoke to the vet this morning and we agreed we stick to 3units 2 x daily, I test her and call him on Tuesday noon to update him about her number. I don´t want to blame him, I think he´s trying his best and he´s available almost all the time, I can call him almost 24/7 but it seems not to be enough...
I would be very grateful for your suggestion. Thanks a lot for your time and advice!
Best from Prague. Helena
