In various cultures throughout the world there is the widespread belief that animals, including companion dogs, are more likely to bite when under the influence of a full moon

What is already known on this topic

  • The research literature on the effect of lunar phase on human behaviour has mostly shown no association

What this study adds

  • In Australia no association exists between lunar phase and dog bites requiring hospital admission
