This is a fast moving and funny movie that's a truly great comedy, worthy enough to stand alongside This is Spinal Tap.
This one has everything. Conflict-who will win the dog show? Humor, and lots of it. Fred Willard again proves he needs his own TV show (nay, his own channel) as a dog-show commentator so obliviously stupid he's lovable. Eugene Levy and Catherine O'Hara are perfect as your typical, middle-class east-coast family; Eugene's plays somewhat of a "loser", Catherine's great as the promiscuous wife. Jennifer Coolidge is pretty funny as the "glamorous" lesbian who can be aggressive in subtly funny ways.
The best thing about this movie is that it's truly humorous with truly funny actors. These people aren't puppets for lame sex jokes (well, not counting both gay couples) they're funny because they (as in the talented actors, the whole lot of 'em) inherit their characters and give them a life of their own. I mean, I bet that Eugene Levy came up with his character's two left feet on the spot because he knew he had to make a somewhat pathetic character even more pathetic. There's an absolutely pointless scene where Guest's character, a southerner/hunter/ventriloquist, talks to the camera about how he used to stay up all night naming nuts. It's funny though, because it makes no sense but somehow falls in line with the character.
This is a great comedy that makes few cheap shots but is consistently funny through and through.
The DVD has a pretty entertaining commentary with Guest and Levy, and some funny deleted scenes (look for the one where Hamilton tells Posey about "a saying my father used to say"). Those extras are enough for this disc though, and the price is great. Buy this inspired and funny comedy.
