Our lab, Ceili, will be 10 in July. Once before she started this behavior of being skittish to walk into a room or around a table. We thought it might be that she was having trouble seeing but she can still catch a treat that is thrown to her. For example, she will come to the door of our study, start to head in and then do a quick back-up. She will do it 5-6 times (or sometimes more) before entering the room. She started doing this a year ago and then it went away but now she is doing it again and it seems more pronounced. What is funny is that she is wagging her tail the whole time that she is doing the go forward and back-up move. It has even been happening with her food bowl. We all know how labs LOVE their food but the last few mornings she will go forward and back-up many times before she goes forward bravely to eat her food. It does not happen all the time but multiple times a day entering different places. Other than this she is a very healthy and happy lab! Any thoughts?
