Hey there. My Murphy was doing really well for quite some time on 2.5u of Prozinc. I even backed off of testing him b/c his spirits were up, water & food consumption normal, etc., etc. I did notice that his gums were irritated, and that had me nervous about infection causing problems with his diabetes. So, I had his teeth cleaned in March. I started monitoring again during that time, in case the antibiotics caused any changes in BG. All seemed ok for a while. Then, I started noticing him at the water bowl again. Not ALL the time (like he was before being diagnosed with diabetes), but more often than I'd seen in a while. (His spirits were good and he had actually started jumping up on our bed. That is a big deal b/c he has neuropathy and could only make it as high as the sofa before.) SOOO, I started actively testing him again. His numbers have been high and not getting any better. During this time, I was at the end of a vile of Prozinc. I wondered if the new vile would make a difference- "fresh batch"?? As you can see by his chart, his numbers are high. I have increased his dosage and it seems to make a difference here and there, but nothing steady at all. Is it possible I have started giving him too much? In the past, I have increased his dosage only to have him "balance back out" to a good level at 2.5 units. Side note- since I've increased his dose over the last week, he's had some issues with runny poop and seems a little more sleepy. Otherwise, he seems ok, still jumping up on the bed and playing with his furry brother and sister. Any obvious advice? Thanks so much!!
