Archive: https://archive.today/0p1G0 From the post: >>A man was seen being attacked by a rabid fox in his own yard after the wild predator went after his dog. Surveillance footage from March 20 revealed the startling moment Michael Martin got into a frightening scuffle with an infected fox that invaded his property in Kennebunk, Maine. Martin first caught the unhinged animal going after his Golden Retriever, Teddy, in his yard, as the dog was heard barking while the fox hissed and pounced on the pup. He quickly ran out for equipment to get rid of the fox, but when he returned home, the vicious animal was waiting for him in his driveway. Just moments later, the fox pounced on Martin, raced around his feet and appeared to bite him as the worried owner jumped around in fear. Martin then ran to get his gun and shot the fox in order to protect himself and his dog.
