Yup, thats what Lynn is doing. She used to be horrible about staring at shadows. She would sit there for 15 to 20 minutes easily! Then someone told me that is not a good thing, and I need to stop her. (on chaz maybe) So I have interrupted the behavior and give her something else to do. She still has a shadow fetish but nothing like she used to have. Well, today she keeps digging on top of a shadow. I keep interrupting her, and she will go dig at another! She has had plenty of exercise today! So I dont know what her deal might be. I think I am going to end up making her stay in the bed room with me (where the computer is) for a while. away from the shadows Besides possible boredom, why does she do this? please dont tell me that I have a dog with a chemical imbalance AND another dog with OCD.
