->''"Some pets deserve a little more respect than others."''
-->--'''Film {{Tagline}}'''

A 2000 {{mockumentary}} film directed by Creator/ChristopherGuest and written by Creator/EugeneLevy with Guest co-writing. It has many of the same cast and crew as Guest's other films, including the earlier ''Film/ThisIsSpinalTap'' and ''Film/WaitingForGuffman'' and the later ''Film/AMightyWind''.

The movie follows five dogs and their owners who enter the annual Mayflower Kennel Club Dog Show, and the unique relationship the people have with their dogs and with one another. ''Best in Show'' features a heavily improvised script that results in some wild tangents concerning everything from red pistachio nuts to a grisly description of a body being flung off a skyscraper.

!!Tropes:

* BookEnds: The film begins and ends with the Swans talking to a therapist about their problems with their dog.
* CampGay: Scott. By contrast, his partner Stefan is more of a StraightGay.
* CuckoolanderCommentator: The ex-Football player announcer.
* GettingCrapPastTheRadar: "[[ThisIsForEmphasisBitch Bitch]]" is the actual term for a female dog. When writing the script, Guest and Levy milked this for all it was worth.
* {{Improv}}: Guest has his actor improv from general outlines.
* LadykillerInLove: Cookie is the female version. She can't go anywhere without bumping into someone she's had sex with, but she settled down and married a goofy, straight-laced guy, whom she seems to genuinely love.
* LargeHamAnnouncer: They make the dog show even funnier, as they're an OddCouple - one a genteel English dog-breeding expert and the other a desperately misplaced American Football commentator.
* LipstickLesbian: Sherri Ann, as revealed when she plants a kiss on Rhapsody In White's much more butch trainer.
* LiteralMetaphor: In their first interview Cookie and Gerry joke about his inability to dance and mention his "two left feet"--and the camera pans down to show that Gerry has ''two left feet''. He used to walk in circles when he was a kid.
* {{Mockumentary}}: It's Guest, after all.
* NoodleIncident:
** The hotel manager (Ed Begley Jr.), when discussing the difficulties cleaning up after a dog show, mentions an unnamed rock band (probably a Spinal Tap reference). Details are sparse, and include only the comment that "they probably didn't realize there was a toilet in the room", as well as something about "roasting a goat," and how how hard it was to get the smell of charcoal and cumin out of the curtains.
** Frequent un-elaborated-upon references to Cookie Fleck's past sexual history as she coincidentally encounters numerous former partners.
* NoCelebritiesWereHarmed:
** Buck Laughlin bears more than a passing resemblance to Joe Garagiola, the former baseball player and announcer who provided commentary for the USA Network's coverage of the Westminster Kennel Club Show for many years.
** Sherri Ann Cabot is obviously based on Anna Nicole Smith.
* ProductionPosse
* ReallyGetsAround: Cookie Fleck, before she married Gerry. To his suppressed but obvious frustration, they keep meeting her former partners wherever they go.
* RunningGag: Many of them.
* SeriousBusiness: The Mayflower show is as serious as it gets.
* SpiritualSuccessor: To Guest's previous {{Mockumentary}}, ''Film/WaitingForGuffman''.
* TrophyWife: Sherri Ann Cabot is a spoof example in the GoldDigger vein, and, unusually, [[spoiler:is cheating with another woman, not a man.]]
