The free audio book 'Teddy and Stanley's Tall Tale' includes soothing syllables designed to lower stress in canines.
Laura Quinn, working with pet behaviourist Karen Wild, spent years analysing speech patterns so they could write a story perfect to calm and relax dogs upset by fireworks.
"Dogs understand certain sounds as calming," the Sun quoted Wild, who created the story as saying.
The book tells the heartwarming story of a towering dog called Stanley and his smaller friend Teddy.
Dogs can hear the audio book read by actor Simon Callow on YouTube, or their owners can download a version to read to their pets themselves.
It is designed to be played to dogs on and before Bonfire Night to minimise the stress caused by fireworks displays.
The bedtime story is said to draw on years of scientific research into dog behaviour, using "proven animal psychology techniques, signals and bioacoustics".
Dog owners who choose to read the story to dogs themselves are advised to pretend they are "talking to a two-year-old child, as if the child is rather shy".
