Not only edited in Sony Vegas 8, but a NY Times Critic's Pick, no less.
A quote from the review, but read it in its entirety:
"The film’s hand-drawn animation by the directors Paul and Sandra Fierlinger (they are married) and Mr. Plummer’s understated conversational voice combine to make “My Dog Tulip,” which opens on Wednesday at Film Forum in the South Village, one of the most sophisticated dog movies ever created."
