Why Do Corgis Butts Float? The Scientific Explanation (2023)

We all know corgis are exceptional dogs. They have short legs, long bodies, and big ears. But did you know that corgis butt floats?

Here is what we found out:

Corgi butts are buoyant because they have 80% fat in their bodies. This is due to their unique body shape and size. Corgis have a low center of gravity, which helps them stay afloat in the water. Additionally, their short legs and long bodies make them more buoyant than other breeds.

That being said, in this article, we’ll dive deep into this amazing topic to explore why corgis float and what’s the reason behind it. 

Let’s get started

Why do Corgi’s butts float?

The answer lies in their genetics. Corgis have short legs and large heads, which causes more weight to be distributed along their backs. This makes their hindquarters extra heavy, which causes the fat to be distributed toward the back end of their bodies. 

This high-fat concentration gives corgis such buoyancy that they can float in water. As a result, corgis float when they’re swimming in water as a way to conserve energy and stay afloat longer.

Why do corgis have big butts?

Corgis are known for their adorable fluffy butts, which look great in a pool float! But why exactly do Corgis have such big bums? It is actually related to the breed’s herding instincts.

The big bottom serves as a sort of rudder while they are running short distances between sheep or cattle. This helps the Corgi maneuver quickly and accurately while chasing livestock.

The breed was originally bred to be a herding dog. Therefore it has certain physical characteristics that make it an especially good herder, such as its short stature, long body, and big butt.

So the next time you see a big corgi behind in its bouncy, jiggly glory, you can appreciate that it is adorable and has a functional purpose outside of lounging comfortably on a float!

Can Corgis swim?

Yes, Corgis can swim! In fact, they are decent swimmers due to their buoyancy. Corgis have a natural ability to stay afloat in water.

However, despite the affinity for water, it is important to note that not all corgis are natural swimmers. Some may be more hesitant or scared of the water, so it is important to introduce them to swimming slowly and with patience.

Due to their short legs, Corgis cannot really ‘doggy paddle,’ so it’s safer for them to use a life vest or dog float when enjoying the water.

A life vest or corgi butt float will keep your pup from sinking down in the water and help them stay safe while having fun.

Things to consider when buying a dog swimming dress:

  • Corgis can swim, but their short legs make it difficult for them to paddle.
  • A dog swimming vest can help your Corgi stay safe in the water.
  • Make sure the swimming vest fits snugly and doesn’t impede movement.
  • Look for a swimming vest with a handle on the back so you can grab your Corgi if they start to drift away.
  • Consider getting a dog life jacket as well for extra safety measures.
  • While corgis are decent swimmers, a swimming vest is always a good idea to help them stay safe in the water.

What is the buoyancy of a Corgi butt?

The word ‘buoyancy’ refers to the ability of an object to float in a fluid. The most common example is a boat floating in the water. The buoyancy of an object is determined by its density and the density of the fluid it is submerged in.

The buoyancy of a Corgi butt is highly dependent on the size of your Corgi. Generally speaking, the larger the Corgi, the more buoyant it will be.

This is because larger dogs have less surface area in comparison to their volume, meaning they are better able to displace a larger amount of water so that their body can ‘float.’

In addition, hairless dogs or those with thin coats (like Corgis) generally have less drag while floating, increasing their buoyancy. So even if your Corgi isn’t large, its low-maintenance coat could help it float on top of the water!

When it comes down to it, there’s really no way to know exactly how much buoyancy your Corgi will have in a pool unless you test it out!

Why do corgis have tiny legs?

The Corgi is a relatively new breed, having been around for less than 200 years. And while they were initially bred as working dogs in Wales, they’ve since become one of the most popular dog breeds in the world.

So why do corgis have such short legs? Well, there are a few theories. One is that their short legs are an adaptation to the rocky terrain of Wales. Another theory is that their short legs were bred into them in order to make them better at herding sheep.

Whatever the reason, corgis’ short legs are one of their most distinctive features. And while they might not be able to run as fast as some other dogs, they more than make up for it with their adorable waddling gait.


Before we move on to the conclusion, we’ve summarized this article into a short list of key points for you to remember:

  • Corgis are decent swimmers, but a life swimming vest is always recommended.
  • The buoyancy of a Corgi butt depends on its size and coat.
  • Corgis have short legs due to their history of being bred as working dogs in Wales.


Corgis are a unique breed of dog with many interesting features. Their short legs and low-maintenance coats make them great swimmers, although they may need a bit of help to stay afloat. With the right swimming vest and some supervision, your corgi can enjoy a day at the beach or pool.
