Your vet needs to determine whether you are dealing with a problem with insulin resistance or of insulin absorption. I find the easiest way to do this is to run serial blood glucose tests after administration of Regular Humulin insulin. This is the best absorbed form, and if an appropriate dose doesn’t decrease the glucose level significantly, then true insulin resistance should be suspected. Infections, hyperadrenocorticism, acromegaly etc. can all cause insulin resistance. Where do you live? Do you have a veterinary endocrinologist or internist nearby?
