An Ethical Dilemma

Please weigh in on the following:

At my apartment complex, they have the usual dog* rules: scoop the poop, keep them on leashes, and so forth. I mostly follow the rules. Every once in a while, I forget to bring a baggie for scooping (but I always take Rowen to the same spot, so I usually pick it up the next time I'm there). I also occasionally let Rowen off leash to play in one of the grassy "bowls" (rain collection areas) with a couple of other dogs and their owners. She's mostly good about staying in the grassy area; I just have to watch that none of the nondoggy neighbors walk by because she feels the need to greet them with lots of jumping. The grassy area is sort of set back and I haven't seen any of my neighbors other than the other dog owners for weeks, so this really isn't so much of a problem.

Here's my dilemma: One of the other residents has two little dogs---a miniature daschund and a fluffy white thing. He lets them play in the grassy area outside of his apartment (a different area than where Rowen plays). And at least twice now, they've run out into the street when I've walked by with Rowen. I'm not worried about them saying hi to Rowen; both of them put together are only about half Rowen's size. But I am worried about them getting hit by a car. It would be very easy to not see them running out from between the parked cars; I've almost hit another dog in our complex that way.

I've mentioned to the dogs' human that he should really keep them on a leash. He doesn't seem concerned.

So: He's clearly breaking a rule. But it's a rule that I've also broken. And I don't want to ruin the fun for all the other dog owners who are able to keep their dogs under control and out of harm. But I also don't want the dogs to get hurt because he was negligent and I kept quiet.

Should I report him to the apartment management?


*Don't get me started on the unfairness of having a ream of rules for dogs and no rules for the stupid, nasty, dirty cats that walk on my car and harass my dog.
