sorry to hear about your dobe. what food is she on at the moment? science plan isnt the only food out there suitabke for diabetics, there are several, so wait and weigh things up before starting her on a new food. several of the clients we see feed their diabetic dogs on chappie and they do quite well. the most important thing is to ensure the dog has set regular mealtimes.
the occasional treat as long as it was one or two biscuits should be fine, though i wouldnt do this until she is settled, it can often be weeks before the correct dose of insulin etc is sorted.
good luck
