It felt, fundamentally, like Dog Parker solved a problem that didn’t exist. That’s not all that notable — highly ambitious tech people seem to do stuff like that all the time. But what made this iteration of the tech trope so special, to me, is that this was the only one that had produced a prison for dogs.Admittedly, the world at large has been much more open to the idea. When TechCrunch wrote about Dog Parker last year, they called out the single-serving prison’s “internet connectivity” and noted how “through the app, users can view their dog on the web cam to make sure they’re OK” and how the boxes are also “fitted with a UVC sanitation light, which handles surface level cleaning of the Dog Parker between visits.” When Brooklyn Magazine explored it earlier this month, they asked some good, hard-hitting questions. Like: “What if other dogs pooped in there?” And “Is it okay to stuff my best friend in a box?” And “What if I can’t get him out?”

Please, Lord, let this be the day I see a dog trapped in a pop-up prison.

Still, ultimately, BKMag signed off, saluting Dog Parker for its expansion to 30 locations city-wide, and noting the company’s eyeing of 63 other “walkable” cities that may soon be able to take advantage of their temporary app-based jail services.

And now that I think about it — the other day, actually, I was walking into that grocery store down the street when a woman stopped me. She was just buying a couple of lemons, she explained, which she could easily grab from the crates out front, and she had her dog with her, and so she didn’t want to go inside. Would I mind handing the clerk a dollar for her, for the lemons? At this point I should have chucked a casual thumb behind my shoulder and said you know there’s actually a tiny dog prison right around the corner … What I did, like a complete idiot, was say sure.

Full disclosure: I don’t have a dog. You might say my credibility here, now, is shot. But I do know a lot of people who have dogs. They love to talk about their dogs. They do it all the time. One thing I’ve never heard any of them say is I wish there was a locker into which I could insert my dog while I ran errands.

But could I really judge without empirical evidence? So I asked the dog people. Have you tried Dog Parker? Would you? I heard a range of responses. Like: “lol I do not trust these AT ALL” and “I’ve seen them! They scare me!” and “[two hands-on-cheek-in-horror emoji faces].” I also heard, “I saw one in use and was happy to see that they dim the inside of the dog jail so the jailed dog doesn’t attract too much attention. You could argue that the dog jails are the least worst thing for a legitimate problem.”

I then asked two pals, a couple in Fort Greene with an adorable basset hound named Lou, to actually give a Parker a try. They were skeptical: I was told, “You will need to cover the cost of therapy Lou will need after the exercise.” But they went forth. And — Lou seemed totally fine afterward? But he’s a dog, so he can’t talk?

There was only one move I had left. One foolproof reporting tactic. It was time for me, personally, to enter the Dog Parker.

Here’s where I admit something else that might wipe out my credibility: I’m annoyingly claustrophobic. I only go in elevators if I can’t find a workaround. (Said workarounds might include climbing 20 stories or, like, avoiding the function altogether and returning home.) The Dog Parkers are basically my own private Room 101s.

Nonetheless, I marched forward. Last Sunday, on the way back from the store, I left my groceries on the street, downloaded the app, entered my info, and popped inside. I held the door shut (keeping my hand on the handle, of course, in case a panic attack ensued and I needed immediate escape). I took a minute to see the world from the point of view of a dog inside a Dog Parker.

It was cool — 60 degrees, according to the app. It was cozily lit. I didn’t feel like my air supply was going to run out, at least not imminently. I left and went home to think about what I’d experienced, and also to eat some bread.

Then I noticed I had a voicemail. It was Chelsea Brownridge, the founder of Dog Parker, politely but firmly explaining that the Dog Parkers were designed for dogs, not humans, and that I’d violated the terms of service and that I should not climb inside of one again. The next day, we texted and I explained my motivations and my investigations. She said “we take pet care very seriously” and I agreed that was important, and also that it was probably dumb of me to go inside. She also asked me “How was your stay? :)” which I found thoughtful.

She agreed to answer some questions for this piece. And I emailed her really just the one pressing thought. Have you heard the criticism that Dog Parker can feel, from the outside, like a prison for dogs?

“We do hear them called that from time to time,” Brownridge wrote back, “but it’s always amazing to see how quickly people ‘get it’ and eat their words as soon as they actually give us a try. We’ve even had people see us at events and say ‘my dog wouldn’t like that’ and stand there with a look of shock on their face when their dog walks right in and sits down (they like the air conditioning).”

She sees Dog Parker as “the exact opposite of a prison,” she wrote, because it means you can bring your dog out with you anywhere you go (as long as it is near a Dog Parker).
