Manners around dogs work both ways. You don't want your dog to jump, to sniff intimate human places, to lick indiscriminately (I don't mind licking. Elka just needs to stop when asked.), and especially not to bite.
Dogs don't want humans to approach them too fast, move erratically, hit them, that kind of thing.
These are the basic, mostly understood manners. Then there are the laws, which allow for the existence of dogs, but more or less don't want them to exist. In my town, a dog is not to be on a leash longer than 6 feet off of the owner's property, for example. There is nowhere "sanctioned" to take dogs to run, if your yard is small, or if you have an apartment. Of course you have to pick up dog waste not on your property. Also, "nuisance barking" is ticketable, but that doesn't seem to be enforced very much, judging by the block that I think of as "the gauntlet", as there are six or more dogs barking in houses anytime anybody is on that block. There don't seem to be laws like that if a child is misbehaving, and I firmly believe it's up to the parents or caregivers to train a child, much the same way owners are expected to train their dogs. How else will either learn how to behave in public?
