Turbo, an 11 year old doberman, wandered away from his home on Marco Island, Florida. He was found fifteen hours later in a canal not far from his home, alive but exhausted. The dog likely spent the entire night in the canal before a neighbor rescued him after being alerted by dolphins who kept the stranded dog afloat for several hours. Turbo, though tired, responded well to "pupperoni" treats.
