Nothing has ever happened to that dog as far as the color brown goes, I've had him since he was born. I just don't think he registers the color brown well and doesn't like it. He's a big baby in most instances. He intimidates people though, carries a brick around the yard or a turtle if one's available. Heck he piled off into a pond by the house one day after a 4' alligator.
Heck his momma didn't like my Ex-wife from day one. She sat on the couch between us and growled at her. I should have listened to the dog, she was much smarter than I was.
