My 12 (?) year old Oreo was just diagnosed yesterday. Glucose was 561. I switched him to canned food last night along with two units of Vetsulin 2x/day. I took him to a clinic today for another glucose test and he was at 440. My vet made it sound like he'll be insulin dependent the rest of his life. I surprisingly have no problems giving him the injections but when I go back to work in the spring I'm gone for more than 12 hours at a time almost every day Monday thru Friday. I'm terrified as to what could happen if this can't be regulated by diet alone.
