Romeo appeared in the Alaskan community near Juneau, and “was a bit of a flirt, and like Shakespeare’s Romeo seemed to fall in love with”…Juliet, a yellow Labrador. Normally wolves fight with canines or eat them, but Romeo wanted to play and had his favorite humans and dogs. He would keep his distance from people but came within touching range of the author, however, Nick Jans didn’t try to pet him. He respected the wolf’s wild behavior. Romeo “would run into the middle of a game of fetch and steal the tennis ball, run off with it, throw it up in the air, and bat it with his paws.” He had his own toys that he’d bring to Jans and his friend, Harry Robinson. Romeo would pick up one of his toys, knowing how to fetch, and bring it to Harry to throw, .
The average life span of a wolf is three years and he was full grown when he came to the community. He visited them often for six more years, so he was at least eight years old at the time of his death. They didn’t feed him. He would leave for several days, apparently finding his own food.
