OCD???

Do you believe that dogs can have OCD (obsessive compulsive disorder)? If not, you may after this story:
We left for work this morning thinking that everything was normal in our lives. Apparently we were mistaken. After work we came home and were standing around talking. After a while Brian sat down at the kitchen table. However, he didn't sit in his usual chair, but in my chair at the opposite end of the table. Oscar came up to him and started barking. So Brian got up, checked his dish to make sure he had food and water and then sat back down. Oscar kept barking at him. Brian couldn't figure out what his problem was, but finally in exasperation he got up and moved to his regular chair. It was at this point that that the dog finally calmed down, went to his bowl and began to eat. He will usually go to his dish and eat whenever Brian sits at the table. As long as Brian is in the correct chair all is good in Oscar's world. At least I don't have to worry about Brian stealing my chair. Maybe it's the ideal diet plan for Oscar.
