While I donāt disagree with you, my vet very much followed the same protocol. My understanding is diabetes in dogs and cats are worlds apart despite being the same in many ways. We did opt to pay the extra for the FreeLibre monitor for our dog, especially in the first 6-8 months while we learned her patterns. It got to the point where I could pretty much guess her levels within 10 points no matter the time of day because I got to know the curve so well. So now she is on a pretty level dose (down to 2.5 instead of the 5 we had to have in the beginning).
I may have already mentioned this, but I soak a batch of chia seeds each week and she gets about a tablespoon on top of her food twice a day. They are supposed to help regulate blood sugar and they do seem to be working! We never went with the diabetic food, we opted for a weight control food instead with our vetās blessing (no worries about running out because of a missing or late prescription this way). We use the CORE Wellness brand canned weight control since itās easily obtainable both locally and through Chewy. She also gets a few green beans and a couple pieces of cooked sweet potatoes with her food to help keep her fiber intake high so sheās not acting like we are starving her all the time.
