Dogs and Lemmings

Maybe they learned that their school had dropped its math department. What else might be causing this:

A SPATE of what appear to be canine suicides has animal psychologists in Scotland baffled. At least five dogs have thrown themselves off the historic bridge at Overtoun House in Dunbarton, Scotland, in the past six months.

I don't know what it is about Brian and dogs. He also sent me this:

US prosecutors trying to crack a murder case realised they were barking up the wrong tree when one of their witnesses turned out to be a small dog.
They had been sniffing around Murphy Smith ever since the main suspect sent him a letter from his cell. ...
They sent out a subpoena, and the five-year-old Shih Tzu duly appeared at the Benton County Prosecuting Attorney's Office, led by the defendant's brother.

When he sent it, Brian added, "At least he didn't jump off a bridge when they subpoenaed him."
