Veterinary offices go upscale to care for pets (and their owners).

More than 12.6 million United States households adopted animals from March to December of last year, according to the American Pet Products Association, helping to propel an increase in visits and revenue to veterinary offices.

That heightened demand has drawn investors and others to the market for veterinary services. Landlords who might have spurned tenants associated with unpleasant odors and noise are more amenable to leasing to the clinics after a year when the vets paid their rent while other businesses fell behind. And architecture firms that specialize in the design of vet space are busier than ever.

Tech-savvy start-ups are promising a reinvention of the experience, with phone apps, round-the-clock telemedicine and boutique storefronts with refreshments (for pet owners).

The pet care business is riding a growth spurt: Morgan Stanley projected that it would be a $275 billion industry in 2030, up from $100 billion in 2019, with vet care the fastest-growing segment over the next decade.

“Ten years ago, there was a baby boom,” Arash Danialifar, the chief executive of GD Realty Group, a California company that has leased space to a veterinary start-up, said about the proliferation of shops selling children’s fashion. “Now, it’s all about pets.”
