well I have a little story about an OCD woman I know, who got a dog many years ago. She fell in love with a golden retreiver puppy, and brought it home. She would only let the dog at first stay downstairs, cause she didnt want it to mess up the rest of the house. after spending hours cleaning up after the dog, daily, she decided it would be best if the dog was an outside dog. That dog stayed outside the rest of its life. She wouldnt pet it, cause it was dirty! The dog was given no affection, was never taken off the chain, and was in horrible shape. My inlaws later took this dog in, and she was a mess! The leather collar the dog was wearing removed all the fur from the dogs neck, and it never returned! the dogs name was ashley! and she was such a sweet girl! No matter what she went through as a puppy and a young dog, she always was a good girl! this dog ended up costing my in laws a huge fortune! but they didnt care cause she was a great dog, ashley lived to be 11 yrs old, and was put down two years ago, suffering from cancer!
I am not saying all OCD people are like this, this is just my one experiance I had with one!
