Notes on using our dog age calculator

  • Only available for dogs over 6.8 kilograms
  • The age calculated is only a guide as to how old your dog may be in dog years
  • Only valid for fully grown dogs in healthy weight range for the dog’s breed or build
  • Date is based on a mixed breed dog rather than pure breed
  • Data on which the calculator is based suggests that mixed breed dogs may live significantly longer than pure breed dogs
  • Data on which the calculator has been based were collected from 1980-1990 in the United States and Canada. (As such the information may not necessarily accurately correlate with dogs in Australia in 2010 and later)
