Common Sense Note
Parents need to know that Best in Show is a hilarious but very dry mockumentary about the dog-show world will likely bore kids. There is some cursing, including a notable scene where a father threatens his son with horrific violence and calls him a "freak." One character is depicted as having been promiscuous in her past, and many men come on to her in social situations using coarse language ("I banged a lotta waitresses in my time"), to the consternation of this character's husband. Several characters in the cast are depicted as being gay and there is a very passionate surprise kiss between two female characters who later proclaim each other "dynamite in the sack." This one's best for adults and teens who enjoy dry absurdity, and anyone who has a show dog or is interested in the dog show world.
There is a little bit of sex talk, mostly to one character depicted as having been promiscuous in the past, but nothing too explicit. There is a passionate same-sex kiss and some insults leveled at gay people, as when one character refers to another (gay) character as "prancing around."
Almost nonexistent save for a reference to a long-ago parent's suicide, and one scene where a wound-too-tight dad tries to get his son down from a roof by threatening him with violence: "I'll punch you in the eyes until they're jelly!" he shrieks. There is also some graphic talk about said father's job, which is trying to keep suicides from jumping (usually unsuccessfully).
A few curses: "I s--t you not." There are also several references to "bitch" but usually referring to a female dog
The characters in the movie do love and treat their animals well, sometimes to the point of ridiculousness.
