Low Alert at Dinner, High Alert Before Bed

Bo alerted while we were eating dinner this evening. He came out from under the table for this alert. We thought Austin was going to be high because he was eating dinner but he was 75. This alert came only minutes before we were getting ready to bolus him for his meal. Later in the evening Bo stopped chewing his Busy Buddy gnaw hide bone to come and alert to me. I checked Austin and he was 181.
