The underwater treadmill is one of the most effective tools we have for rebuilding strength after surgery, injury, or a long stretch of reduced activity. Walking in warm water lets your dog exercise with far less weight on sore joints, while the resistance of the water works the muscles harder than the same walk on land. Both Walking Paws Rehab clinics, in Boulder and Denver, have an underwater treadmill, and every session is run by an experienced team member who adjusts water height, speed, and duration to your dog’s stage of recovery.
Hydrotherapy is one part of a plan. Most patients combine treadmill sessions with laser therapy, manual therapy, and a home exercise program. No veterinary referral is needed to get started.
An underwater treadmill is an enclosed tank with a treadmill belt on the floor. Your dog walks in, the door seals, and the tank fills with warm water to a height the therapist chooses. Two properties of water do the work. Buoyancy reduces the load on joints, so the higher the water, the less weight your dog carries. Resistance makes each step harder than it would be on land, which builds muscle without impact. By adjusting water height, belt speed, session length, and incline, our therapists can target very specific goals: offloading an arthritic hip, retraining a limb after surgery, or building endurance for a working dog.
Hydrotherapy is used most often for recovery after orthopedic surgery, including CCL tears (TPLO, TTA, and lateral suture), patella luxation, and fracture repair. It also helps dogs with hip dysplasia and arthritis, elbow dysplasia, tendon injuries, and neurologic conditions such as IVDD and degenerative myelopathy, where the sensation of water against the legs helps a dog relearn where their feet are. Overweight dogs and senior dogs who can no longer tolerate long land walks are also good candidates.
Your therapist sets the water height for the day’s goal and walks your dog into the tank. Most dogs settle within a session or two; treats, a calm voice, and a slow first fill go a long way. Early sessions may be only a few minutes of walking with rest breaks. As strength and endurance improve, we increase time and speed and lower the water so your dog carries more of their own weight. The therapist stands at the tank throughout, watching how each limb is used and correcting compensation patterns as they appear. Treadmill time is usually one component of a longer appointment that also includes hands-on work and exercises.
No. The underwater treadmill is a tool, not a treatment plan, and it is not appropriate at every stage of recovery. Fresh surgical incisions must be healed before a dog gets in the water. Some skin conditions, uncontrolled heart or respiratory disease, incontinence, and a strong fear of water can make it a poor fit. Some conditions respond better to land-based exercise. Your first appointment is a full evaluation; your therapist will tell you whether hydrotherapy belongs in your dog’s plan and when to start it.
Swimming is excellent cardio, but it is not the same as walking in water. A swimming dog uses a paddling motion that works the front limbs heavily and the hind limbs less, and does not practice weight-bearing at all. The underwater treadmill asks your dog to walk with a normal gait, placing each foot and pushing off, while the water supports part of their weight. For rebuilding a normal walking pattern after surgery or a neurologic injury, that matters. Swimming can still be a useful addition later in recovery for fit dogs.
How many sessions will my dog need?
It depends on the condition and goal. Post-surgical patients often come once or twice a week for several weeks; arthritic seniors may continue on a maintenance schedule. Your therapist will lay out a plan at the first visit and adjust as your dog progresses.
Do I need a referral?
No. We do request records and any imaging from your veterinarian or surgeon before the first appointment.
Can I watch?
Yes. Most owners stay for the session, and many dogs do better with their person in sight.
Does my dog need to know how to swim?
No. Your dog’s feet stay on the belt the entire time.
What should I bring?
A towel for the ride home and, if your dog is food-motivated, a few high-value treats.
