So, what are the biggest dogs across the canine world? Here are the pups that take the crown.

Top 5 Biggest Dog Breeds in the World (2024 Edition)
If you’ve ever encountered a truly massive dog, you know the kind of awe these gentle giants can inspire. Towering over most other dogs and often outweighing their human companions, these breeds are as majestic as they are massive. While many people gravitate toward smaller, more manageable pups for ease of care and apartment living, there’s something undeniably captivating about the world’s biggest dog breeds. Their sheer size commands attention, but it’s often their gentle nature and calm demeanor that truly win hearts.

A playdate between the world’s tallest and smallest living dogs went the way of most dog park encounters despite the 3ft (0.91-meter) height difference – lots of tail wagging, sniffing and scampering.
Reginald, a seven-year-old great dane from Idaho, and Pearl, a chihuahua from Florida, are both certified winners in their respective height titles by Guinness World Records. The fact that Reginald is the size of a small horse and Pearl is as small as an apple didn’t stop them from getting along famously.
Pearl, a four-year-old who stands at 3.59in (9.14cm), comes from a long line of short dogs. Her aunt Milly, a previous record holder in the same category, until she died in 2020, also was under 4in (10.16cm) tall.
Both Milly and Pearl weighed 1oz (28.35 grams) at birth.
“I was not expecting to once again have the record,” said Vanesa Semler of Orlando, Florida, owner of both tiny dogs. “That would be like unbelievable.”
Guinness arranged the two-day meet-up between Pearl and Reginald – who also goes by Reggie and measures in at a whopping 3ft 3in (1 meter) – last month at his home in Idaho
