Can anyone recommend other sites for checking the blood glucose? I cannot for the life of me get ear checks with Mr. D.S. Rickelbaum. I have tried several times. I have used the warmth pre test etc nothing. He is not happy. He was started on Vetsulin Thursday (11/5/15) in the pm. He is on 1 unit twice a day. I have been checking blood sugars for over 32 yrs. I am nervous giving insulin without knowing his sugar level. All , and any advice would be helpful. Right now I am watching his intake and trying to watch urine(hard due to multicat house hold). Not currently checking Ketones I need to go to different city /pharmacy. To try to find.
