While you may have assumed that all dogs are natural swimmers, this isn't necessarily true. Yes, some dog breeds do well when they're in water, but other dog breeds may be more likely to struggle in the water no matter how much they dog paddle. Take a look at the list below of dog breeds that can't swim.
Which Dog Breeds Can't Swim?

As a rule, dog breeds that can't swim tend to have some common characteristics, says American Kennel Club (AKC). For example, brachycephalic breeds — those with flat faces or extremely short snouts — are generally unsuited for swimming because it's too easy to get water up their noses, making them a drowning risk. Dogs with large, barrel-shaped bodies struggle to stay afloat, as do dogs with long bodies and short legs. Dogs with long coats or thick double coats can also struggle with swimming. Finally, some breeds simply cannot withstand the shock to their system brought on by a plunge into cold water.
Wondering which dog breeds can't swim? Here are some of the more commonly known dog breeds that might prefer staying on land. If you have one of the following dog breeds listed below, it might be worth reconsidering those regular beach trips.
1. Bulldogs
Both English bulldogs and French bulldogs possess the triple threat of flat faces, barrel-shaped bodies and short legs. In other words, bulldogs simply aren't made for swimming. Only one of these traits would make swimming a challenge for these dogs, imagine having all three! So, in the land of dog breeds that can't swim, bulldogs are king.
2. Pugs
While pugs might enjoy wading and splashing in shallow water, their flat faces make breathing a challenge during the best of times. Add in the exertion of trying to keep their head above water, and it's hard to get pugs to stay above water. For many brachycephalic breeds, including pugs, keeping their faces above water means tilting their heads back so far that their back ends dip too low, says PetGuide.
3. Bull Terriers
Despite belonging to the active terrier group, the bull terrier's combination of short legs and a deep chest makes it struggle to stay afloat. Even the breed's close cousin, the Staffordshire bull terrier, who is a much larger dog, wouldn't necessarily make a better swimmer as the dense, heavy muscle and oversized head on this breed also presents a challenge for these dogs in the water.
4. Basset Hounds
Besides the fact that the body of a basset hound isn't designed for swimming (with their large heads and short legs that make it difficult to stay afloat), the large, floppy ears that are the trademark of this breed are prone to infections when water gets in the ear canal.
5. Boxers
This is another large, athletic breed you might think would be a natural-born swimmer. But the flat face on the boxer makes swimming just as dangerous for these dogs as it is for the more diminutive pug. The struggle to breathe and keep their noses above water means boxers may tire quickly and run the risk of drowning if in the water too long.
6. Corgis
Despite having an affinity for water, neither the Cardigan Welsh corgi nor the Pembroke Welsh corgi are strong swimmers. This is due to the combination of a long body, barrel-shaped chest and disproportionately short legs. So, it's best to let them enjoy splashing in shallow water.
