Corgis really DO have a bubble butt! Science explains why the lovable dog’s rear floats on water 

People swoon over corgis for their “bubble butts,” but this adorable feature is also a built-in flotation device.

Several videos of the little dog have recently been shared online showing that his backside won’t stay submerged — and there’s a science behind it.

Experts claim that a corgi’s butt is made of nearly 80 percent fat rather than muscle fiber, earning it the nickname “bubble butt.”

The excess fat is due to the dog’s short legs and large head, distributing more weight to the rear of its body.

While the fuzzy canines are natural swimmers, pet experts suggest tying a life jacket around their waist when they’re in the water.

Corgis are popular pets because these furry canines are small, sweet and loyal. They grow to only 12 inches in length and weigh no more than 30 pounds.

These dogs are iconic for their long bodies but stubby legs that are surprisingly powerful and muscular.

However, the cute short legs are due to people breeding them for specific traits, which resulted in a genetic condition called achondroplastic dwarfism.

During the Viking invasion 1000 years ago, and the subsequent influx of Flemish weavers, a Spitz-type dog was introduced to some parts of Wales.

These Spitz were crossed with the original Corgi to produce what is known today as the Pembroke Welsh Corgi.

But corgi is a relatively healthy bread that can live up to 15 years.

A deluge of videos of corgis swimming have been shared on social media platforms, leaving many viewers unaware of their floating bottoms.

A video shows the dog swimming in a large pool with its butt sticking out and spinning on the water.

Another clip shows an owner trying to submerge his pet’s backside, with no luck – it just keeps coming out of the water.

There’s a myth going around claiming that dogs’ butts are almost 80 percent air, but that it would be impossible for them to walk if that were the case, reports New pet owners.

Corgis are more prone to weight gain than other dogs – as science has confirmed, fat floats better in water.

Along with excess fat, corgis have a thick double coat that adds to their buoyancy.

The corgi is just one of many dogs bred to have specific traits, and experts reveal just how far humans have gone to create the perfect pet.

We’ve designed 167 different breeds with unique physical and mental traits – many unrecognizable from hundreds of years ago, according to the Science of dogs.

Humans have designed 167 different breeds with unique physical and mental traits – many unrecognizable hundreds of years ago. This includes the basset hound. Prior to human interruption, this dog had shorter ears, a less droopy face, and an arch in its back

Today their bellies are much lower to the ground and their hind legs also appear to be lower with excessive skin with larger floppy ears

Because of this breeding, dogs slowly mutate and deform, and some of these changes have caused these animals excruciating pain.

The pressure to create the perfect dog stems from the American Kennel Club’s standards, the official guidelines for show dogs.

These standards can range from the color of the dog’s eyes, the size of its paws, to the curvature of its tail.

“Today, many breeds are highly inbred and as a result exhibit an extraordinary variety of genetic defects: defects ranging from anatomical problems, such as hip dysplasia, which cause chronic suffering, to impaired immune function and loss of resistance to deadly diseases such as cancer,” James A. Serpell, a professor of animal ethics and welfare at the University of Pennsylvania School of Veterinary Medicine, told WhoWhatWhy.

“The only sensible way out of this genetic dead end is through selective outcrossing with dogs of other breeds, but this is considered an abomination by most breeders as it would inevitably compromise the genetic ‘purity’ of their breeds.”
