"Some place where there isn't any trouble"
Today the movie, Benji: Off the Leash opens around the country, but last night the City of Somerville watched The Wizard of Oz. I can't help but think that, had Dorothy (Judy Garland) had her Cairn Terrier, Toto (Terry, handled by her trainer and manager, Carl Spitz), on a leash, the whole situation would have been averted.1
If Dorothy had had Toto on a Leash, he2 would not have gotten into Miss Gulch's (Margaret Hamilton) garden or chased her cat; Miss Gulch would not have been able to hit him with a rake, and most importantly, he would not have been able to bite Miss Gulch. Call me a wicked witch, but I agree with Miss Gulch: Off-leash, "that dog's a menace to the community". Sure, Auntie Em (Clara Blandick) says, "He's really gentle -- with gentle people, that is," but the fact is that communities have laws to protect people whether they're gentle or not.
As for Auntie Em, she may be "a Christian woman", but she's not an especially responsible guardian to Dorothy--and not because she sends Toto away with Miss Gulch to be destroyed. Contrary to Dorothy's plea--"He didn't know he was doing anything wrong. I'm the one that ought to be punished!"--Dorothy cannot be held responsible for Toto's transgressions any more than Toto can. Dorothy is a child, and, even for a child, no paragon of responsibility: Dorothy runs away from home. "While children can help with some age-appropriate responsibilities, pets require adult caretakers," advises the Partnership for Animal Welfare in Greenbelt, Maryland. The AKC also recommends that an adult take primary responsibility for a pet dog: "Involve your child in the dog?s day-to-day care, but be realistic about how much responsibility he or she can handle." In The Wizard of Oz, it is Auntie Em and Uncle Henry (Charley Grapewin), who are irresponsible.
For dogs the human world is probably a lot like Oz: "some of it [isn't] very nice... but most of it [is] beautiful". Whether your dog is in Oz, in Kansas, or in Somerville, he or she should be on-leash except when supervised in a place where there isn't any trouble. Like Dorothy, Somerville needs "some place where there isn't any trouble": Somerville needs safe and legal off-leash areas, where dogs are protected, both from suffering and from inflicting harm.

2Toto, like the new Benji, is played by a female.
