before agreeing to an xray and spending all that money, please have the vet explain why an xray is required to treat diabetes. I have never heard of that. Is your vet trying to find another condition that Simke may have?...( then said he needed an x ray)
this tells me your vet does not understand that Lantus insulin dosage changes are based on the nadir or low point in the cycle. Only looking at the pre-shot numbers, which is what your vet requested from you, should be given very little weight in dosage changes with Lantus....she later complained chart was too complicated and wanted levels just with time of shot
