So frustrated! We obtained a blood glucose yesterday for the first time on Bella. Had trouble initially knowing where to obtain the sample on her ear. Some online material was very helpful. Good news: it was 141. This morning not so much luck. We stuck poor Bella 5 times at least. Got good samples.. machine kept reading “ error”. We are using a relion micro. She seems ok.. eating small amounts of fancy feast classic. Shes currently off Vetsulin. ( ended up in the vet emergency after Two doses of 1 unit each) Any advice?
