The mockumentary film Best in Show (2000) was primarily filmed in and around Vancouver, British Columbia, Canada, with additional shooting in Los Angeles, California, USA.

Most of the dog-show sequences were shot at the Pacific Coliseum on the Pacific National Exhibition (PNE) grounds in Vancouver, which stands in for the fictional Mayflower Kennel Club show in Philadelphia.

Key specific locations include:

  • Pacific Coliseum, PNE grounds, Vancouver, BC (judging and competition scenes).
  • Anmore, British Columbia, Canada, used for the bait shop locale.
  • Aldergrove, British Columbia, Canada, for the motorhome driving scenes.
  • Other general Vancouver-area exteriors, plus selected scenes in Los Angeles, California.

Production notes indicate the movie was shot entirely on location across Vancouver and Los Angeles, even though the story is set in Philadelphia and at the fictional Mayflower show.
