10 Dog Breeds That Should Not Be Allowed to Swim

While many dogs love splashing around in the water, not all breeds are natural swimmers. Some dogs have body structures, breathing difficulties, or coat types that make swimming risky—even dangerous. Breeds with short legs, heavy bodies, or flat faces may struggle to stay afloat, making water activities hazardous for them.

If you’re planning a beach or pool day with your dog, here are 10 breeds that should not be allowed to swim—or should be closely monitored if they do.

1. Bulldog – The Ultimate Sinker

Bulldogs, both English and French, have a stocky, heavy body, short legs, and a flat face (brachycephalic features). These characteristics make it nearly impossible for them to stay afloat. Their short snouts also make it difficult to breathe properly while paddling, increasing their risk of drowning. Even in shallow water, Bulldogs should never swim unsupervised and should always wear a life jacket if near water.

2. Pug – The Struggling Paddler

Pugs are another brachycephalic breed, meaning their flat noses and short airways make breathing a challenge. Because swimming requires controlled breathing and stamina, Pugs often become exhausted quickly in the water. They also have short legs and a compact body, making them poor swimmers. If they do enter the water, they should always be closely supervised and wearing a flotation device.

3. Dachshund – Too Long, Too Low

Dachshunds may have an adventurous spirit, but their long bodies and short legs make swimming a struggle. They don’t have the leg strength or buoyancy to stay above water for long, and their elongated spine makes them prone to back injuries, especially in deep or choppy water. If a Dachshund must be near water, a doggy life vest is essential.

4. Basset Hound – Heavy-Bodied and Low-Energy

Basset Hounds are dense, low-to-the-ground dogs with short legs and heavy torsos, making them poor swimmers. Their long ears can easily trap water, leading to ear infections. Additionally, their laid-back nature means they’re not enthusiastic about swimming and may struggle to stay afloat. It’s best to keep Basset Hounds on land or only allow them near shallow water with supervision.

5. Boxer – Too Muscular, Too Exhaustible

Boxers are high-energy dogs, but they are not natural swimmers. Their muscular build and short snout make it difficult for them to keep their head above water while paddling. Since Boxers can easily become overheated and exhausted, they risk sinking if they try to swim too long. Always provide a life vest if a Boxer is near water.

6. Shih Tzu – Small, Flat-Faced, and Easily Tired

Shih Tzus are tiny dogs with short legs and a flat face, making swimming dangerous for them. Their long, thick coats can become heavy when wet, pulling them down. Plus, their short snout makes breathing difficult, especially during physical activity like swimming. Even if they enjoy water play, they should always be closely monitored and kept in shallow water.

7. Corgi – Big Body, Tiny Legs

Both the Pembroke and Cardigan Welsh Corgis have long bodies and short legs, which makes swimming a challenge. While some Corgis may enjoy splashing around, their small limbs can’t keep them afloat for long, leading to exhaustion. They may enjoy wading in shallow water, but deep swimming should be avoided without proper safety measures like a doggy life jacket.

8. Chow Chow – Heavy Fur, Heavy Risk

Chow Chows have thick, dense fur, which can become waterlogged and heavy, making it difficult for them to swim. Their stubborn personality may also make them reluctant swimmers, and their short muzzle makes breathing harder when paddling. Even if they enter the water, they should be closely supervised to prevent exhaustion.

9. Pekingese – Built for Lap Lounging, Not Swimming

Pekingese dogs have short noses, heavy coats, and small legs, making them poorly suited for swimming. Their flat face makes breathing difficult, and their thick fur absorbs water quickly, weighing them down. Even shallow pools can be risky for this breed, so keeping them away from deep water is best.

10. Maltese – Fragile and Easily Overwhelmed

Maltese dogs are tiny and fragile, and while they may be able to doggy paddle for short periods, they can quickly become exhausted. Their long, silky coat becomes heavy when wet, and their small size means they lose body heat quickly in water. Supervision and a flotation device are a must if they are anywhere near water.

Water Safety First

While some of these breeds may enjoy being near water, they lack the physical build or endurance needed to swim safely. If your dog falls into one of these categories but loves the water, always equip them with a properly fitted doggy life jacket and never leave them unattended near pools, lakes, or the ocean.

Knowing your dog’s physical limits and taking precautions will help keep them safe and happy, whether they’re lounging poolside or playing on the shore.
