Hi Jenny, I don't generally make dose suggestions, but it does just look like Chianti's bouncing. This dose is getting him to greens. Getting insulin into him with the B12 will help with the neuropathy. In humans, nerve damage, particularly if it's been going on for a while, can take time to recover. You're doing everything you need to do to help support the recovery of those nerves. Hugs! I know it's tough to see them not feeling well, but you guys are doing a great job with Chianti!
With that 65 at +4.5, seems to validate the numbers in the 80s a couple nights ago. Can you get another test in an hour or so to see if he's going lower?
