I think they should seek a behaviourist. If they missed that warning what other warnings are they missing? Hopefully this is his only problem but it doesn't sound like they would be able to read other signs. A behaviourist, traning, and lots of controlled socialization should help but I think they need to hear it all from a behaviourist you know, so they understand the seriousness of it!
Too lazy to even think of a siggy
