Dr Doug, here's a Cyber-Hug (((((HUG!!!!)))) for your help!! If those strips are accurate, his blood sugar was over 1000 (eeks). The Vet said they'd let me know the results tomorrow; and we can pick up a round of antibiotics at the office. If they had SAID that prostate infections are common in diabetic dogs (rather than give me a lengthy explanation of every possibility of what it *might* be) - I would have said yes to the antibiotics immediately.
Once we get back home, my regular, beloved Vet had said we should do a "curve", to see how well the insulin works for him. Yup, we'll be doing that!
