“The dog actually took the driver to the ground and then he actually lifted the dog up and jumped over the side,” CHP Sgt. Steven Toth said.
That does not sound credible. Most likely the guy decided to jump and the dog did not let go.
Most people do not realize that dogs, espcially trained ones, are fairly easy to defeat one on one. It takes some nerve and sometimes the willingness to get mildy injured, but dropping a dog is not hard.
