The old journalism rule that says it's only news if man bites dog and not vice versa might need a new disclaimer to cover situations such as when a member of the K-9 unit sinks his fangs into a soccer player during a match.

While players from the Caxias club in Brazil confronted the officiating crew to complain about a call, riot police moved on to the field. Look for Caxias striker Vanderlei, wearing No. 9 on the left side of the scrum, to react as a German Shepherd snaps at his upper leg:

The match, which Caxias lost 1-0 to Novo Hamburgo in a tournament for the state championship, was delayed nearly 10 minutes while Vanderlei received medical treatment for the dog bite. The dog is named Nitro, according to the Associated Press report.

Amazing enough to learn that a cat survived a fall from 19 stories. Even more incredible that it sustained no broken bones or serious injuries.

Then there's this expert theory on why falling from higher than nine stories actually gives a cat a better shot of surviving.

Commitment and attachment to one's dog can reach admirable levels, but a moment this week in the Iditarod showed just how far one owner would go to keep his prized pup alive.

Scott Janssen (seen at right with his sled team at the start of the race) was forced to make a decision when his dog collapsed while they were making their way down the Dalzell Gorge in Alaska. Marshall, Janssen's 9-year-old husky, suddenly fell in a heap in the midst of pulling hard at Janssen's sled.

"Boom! Laid right down. It was like a guy my age having a heart attack," Janssen told the Anchorage Daily News. Janssen is an Anchorage funeral home owner, who has dubbed himself "The Mushing Mortician."

When he rushed to Marshall's side, the outlook wasn't good.

"I know what death looks like, and he was gone. Nobody home," Janssen, an Iditarod sophomore (he finished 42 out of 47 last year), said.

For a musher devoted to his dogs, it was a heart-wrenching moment at the worst possible time. The Iditarod is a grind, forged by the will of the musher and his dogs, and the bond they share.

"I was sobbing," he said. He began mouth-to-snout CPR -- compressing the husky's chest and doing his best to breathe life into him. "I really love that dog."
