The vet did not want us taking his BG every day as she said it is unlikely to change with his diet being exactly the same every day (although after reading on here im not sure I agree). Today we are doing our curve and I did our first reading before I fed and did the shot (we feed and then do shot after) and it was 130. Now I am wary about giving him insulin because his BG is in our goal zone? will that change after feeding? Should I recheck after he eats before shot?
