[1] In 1896, Dr. Samuel Johnson, a veterinarian in New York City, offered his apple orchard in Hartsdale as the gravesite for a grieving client, whose dog had died, as animal burials were not permitted in the city.

After recounting the story to a friend who was a journalist over lunch, a news article was published in 1898[4]: 1  and later was picked up by The New York Times on September 3, 1905.

[6] In the wake of the ensuing publicity, Dr. Johnson received hundreds of requests for pet burials and set aside more of his land until the Hartsdale Canine Cemetery was incorporated on May 14, 1914.
