Is This A Chesapeake Bay Retriever?

On February 9, a 10-yr-old girl was severely injured by a dog described as a Chesapeake Bay Retriever. Another girl suffered a minor bite wound.

Not much is known about the attack. The dog was let out of his kennel and apparently began attacking the 10-yr-old girl, whom he did not know.

The dog is 2-yrs-old and male.

This news story posts a video which includes Charlie, the Chessie. You can view it here.

So far as I know Chesapeake Bay Retrievers are not that common. I have met five Chessies. Three belonged to an animal control officer who loved the more reserved, more protective Chessies and rescued them anytime they ended up at the shelter. Two belonged to a duck hunter who used them for retrieving downed waterfowl. They were all affable dogs, and I liked them. But they were not quite so galumphy as other Retriever-type dogs I've met. Five dogs is not a statistically significant sample size, so just take those observations at face value.

Perhaps some Chessie or Retriever experts can offer their input - is this dog a Chesapeake Bay Retriever? The quality of the video isn't great, but I can't help but think this is either a REALLY poorly bred Chessie or not a Chessie at all.
