In the last week or so Lee has developed a very loud and annoying habit. While we are sitting eating she will come up and bark at us. I swear she barks extra loud. I tried to get a video of her doing it tonight, but since it is not a constant bark, it is periodic barks and I was eating it didn't happen.
My current strategy for dealing with this is a behavioural term called extinction. This means withholding whatever was reinforcing this behaviour. I am assuming this behaviour has been reinforced by either attention or treats, so when she barks, even though it makes my head want to explode I ignore her and pretend nothing happened.
I hope this habit goes away as quickly as it appeared!
