The 1956 novel by British writer J.R. Ackerley describes his 14-year relationship with Tulip, the German shepherd he rescued, Daily Variety reported.
"This is a profound and beautiful love story," said Norman Twain, one of the producers. "It just happens to be between a man and his dog," Twain said.
The independent film is geared to an adult audience. Twain, who is working alongside Howard Kaminsky and Frank Pellegrino, also produced "Lean on Me."
The other voices, to be recorded soon, include those of Brian Murray, Paul Hecht, Peter Gerety and Euan Morton. Animation will follow.
The film is scheduled to be released in December 2007.
