Sabu has shown alot of improvement in his overall health since beginning lantus bid, his weight has come back, he's playing, there is no more excessive water drinking or peeing. He is 100% wet food low carb diet, but his blood tests preshot are erratic and seem to be getting higher and higher especially at night. Has anyone gone through this that can let us know why? The vet doesnt want to do a curve yet but will within the next week or so. Thanks.
