After Kiwi's glucose curve 5 days ago, we were told to raise his dosage of Lantus to 3 units twice a day. For the last 2 days he has been barely drinking and eating about a quarter of his daily intake of food. We tested his BG 9 hours after giving him the 3 units this morning. It was 413. We really don't know how to help him at this point. Everything we have done has been under the recommendation of our vet. We would appreciate any help! Thank you.
