A video with the ominous title "Kangaroo Tries to Drown Dog" has sparked controversy in Australia.
The owner of the pet, who uploaded a pair of clips to YouTube, said Great Dane Max bolted into the wilderness and starting chasing a mob of kangaroos.
Anthony Gill said he got into his car and pursued Max, only to find him circling one of the animals in a small pond.
Though Mr Gill said he and his four-year-old daughter repeatedly tried to drag Max away from the kangaroos, the videos have received scathing criticism from viewers online.
