Since I cant daily test Tubby and I dont really trust Caninsulin. I was thinking of switching to Lev. At say 1u bid or .5u bid. I would not chase his numbers but do like the vet does and do a blood test for b/g every 2 or4 weeks and try to stay under 200. Tubbys symptoms have disappeared but he is still getting thinner. so back to the vet anyways. No rants about not home testing please . I try most days when his ears return to normal.
