IMO, if the dog is going to be knocked down anyways, I would have it done. I don't recommend it as a separate procedure, as it's effectiveness is not certain, but as a supplementary procedure, I think it is wise.
When a dog saves the life of a man, it becomes clear that partnership knows no bounds.
