Dog daycare (or doggy daycare) provides short-term, daytime supervision for dogs, distinguishing it from multi-day kennel boarding or pet sitting services that occur at the owner's home. This industry emerged from traditional kennels in the early 1990s, fueled by post-World War II urbanization that brought dogs indoors, along with a growing population of childless adults spending more on their pets. The first modern facility, Yuppie Puppy Pet Care, was reportedly opened in New York City by Joseph S. Sporn in 1987, with San Francisco also credited for popularizing the trend. Facilities vary widely in their environments, from fully cage-free settings where trained staff supervise group play, to daycare kennels where individual dogs are confined to runs or cages. Additionally, some offer outdoor play areas, while others are completely indoor-only, featuring designated spaces for both play and bathroom needs.
