I have a Lhasa but no diabetics and she is a super smart dog, smartest we have ever had. She understands things u tell her. The other day I said do you want to go with me on a road trip. She laid down and rolled over and was pretending she was asleep I guess. Sometimes she likes to go other she doesn't. She has to be under my feet. If I get up in the night just to go potty, she drags herself off our bed and goes in bathroom then back to our bed. Each and every time. She is not a licker tho, she likes to lay up against you.
