Every asset class was once not an asset class. Office towers, apartments, shopping centers — each was, at some point, just buildings that someone used, unrecognized by institutional capital as a category worth pricing, indexing, and owning at scale.
The clearest, most recent example is self-storage. In a single generation it went from a roadside curiosity to a core institutional asset class — and it left behind a remarkably clean record of exactly how that happened. That record is a map. The dog economy is standing at the bottom of the same staircase.
Self-storage began as a niche service. B. Wayne Hughes and Kenneth Volk founded Public Storage in 1972 after watching mini-storage sheds do steady business outside Dallas and Houston; they started with roughly $50,000 and a single facility in El Cajon, California. For two decades it was a fragmented, mom-and-pop business — useful, unglamorous, and invisible to institutional money. It is still fragmented at the base: even today, single-facility individual owners hold roughly half of all U.S. facilities, while the hundred largest operators control only about a third.
A real economy with real demand. No recognition. Sound familiar?
Here is the rung most people miss, and it is the most important one.
In 1992, the first Self-Storage Almanac was published — explicitly, in its own words, to help operators run their businesses and “to show that self-storage was evolving into a growing real estate asset class of its own.” Read that again. Before the institutional capital, before the consolidation, someone created a reference instrument whose deliberate purpose was to make the sector measurable and to name it an asset class. It catalogued the supply, tracked the demand, standardized the vocabulary, and assembled the scattered facts into one place where an investor could finally see the category whole.
The Almanac made self-storage measurable. That is what a legibility instrument does — and it is the rung that has to exist before any of the rungs above it can hold weight.
Legibility lets capital in; a vehicle gives it a door. When the real-estate limited-partnership market that had funded Public Storage for two decades dried up in the early 1990s, Hughes reorganized the partnerships into real estate investment trusts, and in 1995 merged them into a single publicly traded REIT. That move unlocked liquidity and institutional access — and, just as importantly, it created a public data trail. Quarter after quarter of REIT filings became the longest continuous public record of self-storage performance in existence. The vehicle didn’t just raise capital; it manufactured the very evidence the next rung would stand on.
Then came the shock that supplied the proof. In the 2008 financial crisis, while the broad real-estate market collapsed, self-storage REITs were among the only property sectors to post positive total returns — with revenue down on the order of a few percent while many other businesses lost 40 to 50 percent. The resilience that operators had always claimed was suddenly visible in public numbers, in the worst conditions imaginable. The demand drivers self-storage people summarize as the “four Ds” — death, divorce, downsizing, dislocation — turned out to be exactly the kind of life-event demand that does not switch off in a recession.
A caveat the honest version keeps: resilient is not the same as recession-proof. Occupancy still slipped from its 2007 peak. But “held up far better than everything else, when everything else was on fire” is precisely the property that makes capital fall in love.
After 2008, the capital came. Private equity, pension funds, and institutional money flowed into the top markets; firms partnered with the storage REITs to buy and build; core-market assets began trading at cap rates close to office. The fragmented mom-and-pop base became a consolidation opportunity — and it still is. And only after all of that does the final rung appear: the advisory and service layer, the specialist brokers and the capital-markets desks that exist to finance and trade a now-recognized asset class. When a firm publishes a self-storage capital-markets page today, it is standing on the top step of a staircase that took thirty years to build beneath it.
Strip the self-storage story to its mechanics and you get a repeatable playbook:
Now lay the dog economy over that map.
Step 1 is already here. The dog-care economy is a fragmented, operator-driven sector — boarding, daycare, and kennel businesses (NAICS 812910), overwhelmingly independent — sitting on top of genuinely non-discretionary demand across some 71 million U.S. dog-owning households. It is a roughly $80–100 billion economy that behaves like a utility: when COVID hit, dog food was hoarded and rationed like toilet paper, with the industry pleading against panic-buying. That is the self-storage “four Ds” resilience, in a different sector.
Step 2 is being authored right now — by this library. The dog economy has had no Almanac: no standardized operator benchmarks, no consolidation tracking, no single sourced place where an investor can see the category whole. The $100B Dog exists to be that legibility instrument, exactly as the Almanac was for storage.
Step 3 we already hold. The narrative is named: utility, not luxury; recession-resistant; humanization. South Korea, where pet strollers now outsell baby strollers, is simply the leading edge of the same curve.
Steps 4 through 7 follow recognition. Self-storage got its proof by accident, from a crisis. The recognition can instead be built deliberately, with evidence assembled ahead of the shock rather than after it.
This is a precedent, not a prophecy, and the discipline of the library is to say where the analogy bends.
The instrument differs. Self-storage is real property — REIT-able, collateralized, 1031-able. The dog-care economy is an operating business that happens to sit on real estate; its eventual financial vehicle will not be a clean storage REIT. The recognition mechanics transfer; the instrument does not, and we will not pretend otherwise.
And self-storage got a free legibility windfall: decades of REIT filings handed it a public data trail no one had to build. The dog economy has no such pure public proxy, so its data has to be manufactured — assembled, verified, and owned. That is harder. It is also better, because a dataset you build is a moat you own rather than one you borrow.
Self-storage had to win two fights: convince the world that storage mattered, and then that it was worth pricing. The dog won the first fight more than ten thousand years ago. No one needs to be persuaded that the dog belongs in human life — that case was closed by civilization itself. So the dog economy starts the climb a full flight up, with all of its energy free for the one thing left to do: the economic translation.
Recognition is the catalyst, not the cause. The weight was always there. The staircase is real, it has been climbed before, and the dog is on the first step with a head start no other emerging asset class has ever had.
We didn’t say it. History did. We’re just the ones putting it on the shelf, in order, so the market can finally see it.
