Oh Boy! I had a girlfriend come to the house yesterday with her 1.5 year old daughter to meet Della. Well, Lucas could not keep is mouth off of her! He wasnt biting her, just mouthing her... her arms and legs were covered in doggy saliva...she didn't seem to mind it, but obviously is not desired behavior. I have no idea what his problem was, I could not get him to stop for the life of me! We have had children over before, and he was fine, we stop and see kids on our walks, and he is fine??? Any ideas on what I can do to prevent this in the future?
