The word hydrotherapy simply means treatment using water. In canine rehabilitation, the aim is to use buoyancy, resistance, warmth and controlled movement to help a dog exercise safely and purposefully.
Why water changes the way a dog moves
Buoyancy reduces weight-bearing
When a dog is supported by water, less body weight has to be carried through the limbs. That can make movement more comfortable and allows exercise to begin or progress without placing the same load on joints and healing tissues as land-based work.
Resistance helps build controlled strength
Water creates resistance in every direction. Even slow, carefully controlled movement therefore asks muscles to work. By changing water depth, speed, duration and the type of exercise, a hydrotherapist can alter how demanding a session is.
Hydrostatic pressure can support swollen or uncomfortable tissues
The pressure exerted by water around the body can help provide even support to immersed tissues. Combined with reduced weight-bearing, this can make movement more achievable for some dogs.
Warm water supports comfortable movement
Exercise in warm water encourages circulation and can help muscles and joints move more freely. Treatment is still carefully paced because warm exercise can be tiring, particularly for dogs that are recovering, elderly or deconditioned.
Pool or underwater treadmill?
Swimming provides largely non-weight-bearing exercise and can be useful where a dog needs cardiovascular work, general strengthening or movement without normal ground impact. An underwater treadmill allows more controlled walking patterns while water depth reduces the load carried through the limbs.
The most suitable option depends on the dog, the condition being treated, the stage of rehabilitation and how the dog responds to the environment.
What is monitored during treatment?
Hydrotherapy sessions are adjusted according to the dog’s movement, confidence, fatigue and clinical presentation. Rest periods are used as required and treatment is progressed gradually rather than by simply increasing exercise every visit.
Veterinary referral
At Suffolk Canine Country Club, therapeutic hydrotherapy is undertaken with veterinary referral. This gives the hydrotherapist relevant medical information and helps ensure treatment fits safely alongside the dog’s wider veterinary care.
