I feel for you I am going thru the same thing I just found out two wks ago my yellow lab has diabetes it was 500 when they tested her. She has been on insulin twice a day and in the vet's all day for glucose monitoring to checked her levels. I am still stressed out but, I know in time it will be better so try to hang in there as soon as they get her level down you will see improvement liked I did it just takes time. My baby is seven yrs old so we were really worried too. Good luck.
