Swimming for Dogs: Benefits, Safety Tips and Getting Started

Swimming is widely regarded as one of the best forms of exercise available to dogs. It provides a full-body workout that engages muscles from nose to tail while placing virtually zero stress on the joints. For this reason, veterinary physiotherapists regularly prescribe swimming and hydrotherapy for dogs recovering from orthopaedic surgery, managing arthritis, or dealing with obesity.

"Just five minutes of swimming gives a dog the equivalent cardiovascular workout of a 20-minute walk. It is the single best low-impact exercise we have for dogs with joint problems, post-surgical patients, and overweight pets." — Dr. Sarah Chen, DVM

The buoyancy of water supports up to 90 per cent of a dog's body weight, which means arthritic or elderly dogs that struggle to walk comfortably on land can move freely and painlessly in water. Swimming also builds cardiovascular fitness, improves muscle tone, increases flexibility, and provides outstanding mental stimulation — a tired swimmer is a content, well-behaved dog.

Beyond the physical benefits, swimming is a wonderful bonding activity. Many dogs that are reactive or anxious on lead become calm and focused in water. If your dog has breed-specific exercise needs that are hard to meet through walking alone, swimming can be the perfect complement.

While many dogs take to water naturally, not all breeds are built for swimming. Understanding your dog's physical traits helps you set realistic expectations and take appropriate safety measures.

Natural Swimmers

Breeds developed for water work tend to have webbed feet, water-resistant coats, and strong, rudder-like tails. These include Labrador Retrievers, Golden Retrievers, Portuguese Water Dogs, Irish Water Spaniels, Newfoundlands, and Standard Poodles. These breeds often take to water with minimal encouragement and can swim for extended periods.

Capable but Cautious

Many medium-to-large breeds can learn to swim well but may not be instinctively drawn to water. German Shepherds, Border Collies, Australian Shepherds, and Boxers often fall into this category. They benefit from a patient, gradual introduction and a canine life jacket for confidence.

Breeds That Struggle

Brachycephalic breeds — Bulldogs, Pugs, French Bulldogs, Boston Terriers — have short snouts that sit close to the waterline, making breathing difficult. Their heavy, front-loaded bodies and short legs also make swimming exhausting. These breeds should always wear life jackets and only swim in very shallow, calm water under close supervision.

Small breeds with thin coats, such as Chihuahuas and Italian Greyhounds, lose body heat rapidly in water and should only swim in warm, shallow pools for short periods. Dachshunds and Corgis, with their long bodies and short legs, can swim but tire quickly and are prone to back strain.

Regardless of breed, never assume your dog can swim. Every dog should be introduced to water gradually and given the option to exit at any time.

A positive first experience with water sets the foundation for a lifetime of enjoyment. A negative one — being thrown in, forced, or frightened — can create a lasting fear that is very difficult to overcome.

Step-by-Step Introduction

• Start shallow. Choose a calm, shallow body of water with a gentle slope — a lake shore, a purpose-built dog pool, or even a paddling pool in your garden. Avoid rivers with currents or waves for the first introduction.
• Wade in yourself. Dogs are more likely to enter water if their trusted human is already in it. Wade in to ankle or knee depth and encourage your dog with a happy tone and treats.
• Use a favourite toy. Toss a floating toy a short distance into shallow water. Many dogs will wade in to retrieve it without realising they are swimming.
• Support their body. When your dog is in water deep enough to swim, place one hand under their belly to support them. Many dogs panic the first time their feet leave the ground and paddle only with their front legs, causing their back end to sink.
• Keep sessions short. Five minutes is plenty for a first swim. End on a positive note with praise and treats.

Never drag, push, or carry your dog into deep water. This can trigger a panic response and create a dangerous situation for both of you. Let your dog set the pace, and celebrate every small step forward. Some dogs take weeks to become confident swimmers — patience is essential.

Water-related accidents are among the most preventable pet emergencies. Taking basic safety precautions protects your dog every time they swim.

Life Jackets

A well-fitted canine life jacket is essential for open-water swimming, boat trips, and any dog that is not a confident swimmer. Look for one with a handle on the back (so you can lift your dog out of the water quickly), high-visibility colouring, and adjustable straps that allow free leg movement. Even strong swimmers should wear life jackets in open water where currents, waves, and fatigue are factors.

Pool Safety

If you have a backyard pool, ensure your dog knows where the exit steps or ramp are. Dogs that fall into pools often panic and swim along the edges rather than toward the steps. Practise showing your dog the exit point multiple times. Pool covers can be extremely dangerous — a dog that walks onto a cover can become trapped underneath. When the pool is not in use, a secure fence is the safest option.

After Every Swim

• Rinse thoroughly. Chlorine, salt water, lake bacteria, and algae can all irritate skin and cause ear infections. A freshwater rinse after every swim is non-negotiable.
• Dry the ears. Moisture trapped in the ear canal is the primary cause of swimmer's ear (otitis externa) in dogs. Gently dry the ears with a soft cloth or use a vet-recommended ear drying solution.
• Watch for water intoxication. Dogs that repeatedly fetch toys from water or snap at waves can swallow dangerous amounts of water, leading to hyponatremia (water intoxication). Symptoms include lethargy, bloating, vomiting, and loss of coordination. This is a medical emergency — seek veterinary care immediately.

Hydrotherapy — supervised therapeutic swimming — has become a mainstream veterinary treatment for dogs recovering from surgery, managing chronic conditions, or losing weight. Professional hydrotherapy centres use heated pools or underwater treadmills to provide controlled, low-impact exercise under expert guidance.

Dogs recovering from cruciate ligament surgery, hip replacement, or spinal surgery often begin hydrotherapy within weeks of their procedure. The water's buoyancy allows early mobilisation without stressing the surgical repair, which speeds recovery and reduces muscle wasting. Many orthopaedic surgeons now consider hydrotherapy a standard part of post-operative rehabilitation.

For dogs with arthritis and joint pain, regular swimming sessions can maintain mobility, reduce pain, and delay the progression of joint disease. The warm water used in hydrotherapy pools (typically 28-30°C) relaxes muscles and increases circulation, providing natural pain relief.

Overweight dogs also benefit enormously from swimming. Because water supports their body weight, they can exercise at a higher intensity without the joint stress that makes land-based exercise painful. Combined with a calorie-controlled diet, hydrotherapy can achieve safe, sustainable weight loss.

If you are considering hydrotherapy, ask your veterinarian for a referral to a certified canine hydrotherapist. Sessions are typically 20 to 30 minutes and may be recommended once or twice per week depending on the condition being treated. Many pet insurance policies now cover hydrotherapy when prescribed by a vet, so check your plan before assuming it is an out-of-pocket expense.
