Design

The first crate that belongs in your living room.

No wire cage shoved in a corner. Denn is anodized aluminum, architectural lines, and a mesh pattern that looks intentional — because it is. It’s furniture that happens to be a den.

Everything they need

A smart hub for their whole world.

See them. Talk to them. Anytime.

An HD night-vision camera with a wide field of view, plus two-way audio. Pup whining at 2 PM? Pull up the app, see exactly what’s happening, and soothe them with your voice — right through the den.

Alerts before you even have to ask.

Barking, restlessness, temperature spikes — Denn notices the moment something’s off and tells you. No more wondering how they’re doing while you’re at dinner.

Safety

Climate protection that could save their life.

Real-time temperature and humidity monitoring with urgent alerts. A sunny window can turn dangerous fast — Denn checks conditions every 30 seconds so you know before it matters.

It even catches accidents.

Air-quality sensing flags when something’s happened in the den — so you’re never coming home four hours later to a mess nobody caught.

Fan favorite

Treats, delivered remotely.

A built-in dispenser drops a treat with one tap — reward good behavior in the moment, or just because you miss them. Try it. You know you want to.

The Tech Bar

Why crate training

A den isn't a cage. It's where they learn to settle.

Dogs are den animals by instinct — a den introduced the right way works with that instinct instead of against it. Here's what actually changes when it's done well.

Puppy resting calmly inside an open Denn crate

Deeper, longer sleep

A dark, enclosed space that mimics a den helps dogs drop into real rest instead of dozing lightly and startling awake at every sound in the house.

A calmer baseline

Predictable den routines lower baseline stress over time. The payoff shows up everywhere — a dog who handles new people, sounds, and places without spiraling.

Real relief from being alone

A den they choose to settle into becomes a safe home base, not a punishment — which is the single biggest lever against separation anxiety.

Training that actually sticks

Den instinct does half the potty-training work for you, and the focus and impulse control it builds carries over into every other lesson.

Built with the pros

Designed hand-in-hand with the people who know dogs.

Vets, certified trainers, and breeders shaped every decision — so Denn supports how professionals actually recommend den training, especially in the hardest first weeks.

Veterinary science

Safety you can't see coming.

Heat is the danger most owners never notice until it's too late. Working with practicing vets, we made real-time climate monitoring a core feature — not an add-on.

Certified training

Data instead of guessing.

Den training fails when owners are guessing. Trainers shaped the app around what actually predicts success — potty streaks, settling patterns, a real picture of adjustment.

Breeding & puppyhood

Built for the first two weeks.

The hardest nights decide everything. Breeders taught us what 2 AM really looks like — so you can see, soothe, and reward without reinforcing the wrong thing.

“We built Denn after our own puppy's first week home — two people taking shifts on the floor next to a wire cage, guessing. Dogs deserve a better room of their own, and the people who love them deserve to actually know they're okay.”

FAQ

Good questions.

Do I need the app subscription?

The camera, two-way audio, and urgent safety alerts work with the free tier, always. The full training system — anxiety score, sleep tracking, potty analytics, multi-user logging — is part of Denn App. You get 3 months free, then it’s $14.99/mo. Cancel anytime.

What dogs does it fit?

Denn launches in one standard Medium size, comfortable for dogs up to about 40 lbs — from puppies through adulthood. Larger sizes are on the roadmap; join the list at checkout to be notified. Full interior dimensions are on the spec sheet at checkout.

Is it safe for chewers and escape artists?

Yes. The mesh is chew-resistant, the frame is aircraft-grade aluminum, and the latch is designed with trainers specifically to resist clever paws. All electronics live in the Tech Bar, out of reach.

What if my Wi-Fi goes down?

Denn keeps monitoring locally and stores events. Sensor backup power lasts 8 hours, and everything syncs the moment you’re back online.
