Hello, I'm having a predicament I've never run into with Valentino. His numbers were very Normal this morning when I checked before food 150- and 180 after eating. They're usually over 340. I'm waiting to give his dose (4 units Prozinc) and now it is 45 minutes past when he should have had it. Any suggestions? Should I wait until a certain point, or give him smaller dose? He has a tendency to have big drops from his higher morning numbers. Any help from the pros would be appreciated. Of course, it's Sunday so I can't call his vet. @Diane Tyler's Mom – any thoughts?
