Chinker has been switched to Lantus on Feb 8 & I noticed improvements within 2-3 days after using Lantus, less drinking, less urine, not as hungry and more active. Getting to my concern is his dosage, I'm seeing green bgs in the 70s (Feb 21) after about two wks. I called the vet to inform her of what had happen & was told to reduce dosage to .50 because his bg shouldn't go below 100 & that Chinker was rebounding. I'm not convinced what the vet told me is the correct info. Should I lower or stay at the previous dosage. Is he rebounding, on to much insulin?
