Guinness World Records
The tallest and smallest dogs in the world meet up for adorable doggy playdate in America
By Katherine Gross Published 30 April 2025
A pair of pooches from America – tallest dog, Reginald, and smallest dog, Pearl – met earlier this month for a unique doggy playdate that truly demonstrates how new friends can come in all shapes and sizes.
Reginald (Reggie), a seven-year-old Great Dane from Idaho, towers over most other dogs – the Guinness World Records title holder for tallest dog living (male) stands at a shocking 3 ft 3 in (1.007 m) from the floor to the withers.
But his new pal, Pearl, a four-year-old Chihuahua from Florida, holds the title for shortest dog living at just 3.59 in (9.14 cm).
For Dogs, a Passive, Unresponsive Human Face Is a "Bad" Face
Active facial expressions are most likely to keep dogs focused on a person.
A lot of research shows that dogs look at our faces and read our emotions from our expressions. Some new research suggests that a passive, unchanging human face (think "poker face") is interpreted by dogs as a negative expression, and dogs respond accordingly.
KEY POINTS
An active stream of facial expressions is part of the normal communication process between humans.
A still and unresponsive face causes a negative reaction for young human children.
Dogs don't like to continue interacting with a person whose facial response is unchanging and unresponsive.
