OCD Dog

I always used to think that cats were the kings of OCD (obsessive compulsive disorder) until I got Ray. Then I realized that dogs have the same tendencies.
Every time we go to the lake, I let Ray choose which way he wants to go, to the right or to the left. Every single time, Ray chooses right. Until last week when, for no apparent reason, he chose left.
Now, every time we go to the lake, Ray chooses left. Not only does he choose left, but he is absolutely determined that we will go left.
Yesterday morning, I made Ray take the path to the right. For the first quarter-mile, every ten feet or so, Ray would stop and try to pull me back in the opposite direction. But I insisted that we continue to the right. As we got further and further along the path, Ray persevered in trying to get me to go the other way. He would stop every 20 feet, then 50 feet, then every 100 feet. But his resolve never wavered. Even when we were more than half way 'round, Ray would stop short, and try to pull me back the way we had come. Only after much persuasion would Ray continue on the wrong way 'round.  Three-quarters of the way around he was still doing the same thing. Stop. Pullllll. If necessary, sit back on haunches. Then finally, FLOP.
That's taking OCD to a whole new level.
