Underwater Treadmill

Service Explainer

An underwater treadmill allows a dog to walk on a treadmill while partially surrounded by water. Water depth, treadmill movement, session duration, and other variables can be adjusted according to the individual rehabilitation or fitness program. Using an underwater treadmill does not by itself make a session veterinary rehabilitation—the purpose and veterinarian-directed plan determine that.

What is an underwater treadmill?

An underwater treadmill is rehabilitation and fitness equipment that allows a dog to walk on a moving treadmill while partially surrounded by water.

The treadmill provides controlled forward movement while the water changes the environment in which the dog is walking.

At ATC, underwater treadmill sessions may be used in different programs depending on the dog and the purpose of the visit.

What can be adjusted during a session?

An underwater treadmill is not simply turned on at one universal setting.

Depending on the program and individual dog, staff may work with variables such as:

  • Water depth
  • Treadmill speed
  • Duration of activity
  • Rest periods
  • How the dog is guided or supported

In veterinary rehabilitation, these decisions are made within the veterinarian-directed rehabilitation plan.

Why does water depth matter?

Changing the amount of water around the dog changes the environment in which movement occurs.

For this reason, water depth is one of several variables the rehabilitation team may consider when using an underwater treadmill.

There is no single water level that is appropriate for every patient.

Is underwater treadmill the same as swimming?

No.

During an underwater treadmill session, the dog generally performs controlled walking or another directed gait while contacting the treadmill surface.

Swimming is a different form of aquatic activity in which the dog moves through the water without walking on a treadmill belt.

Both fall within the broader category of aquatic exercise, but they are not interchangeable.

Is underwater treadmill always veterinary rehabilitation?

No.

The equipment itself does not determine whether a session is medical rehabilitation.

When an underwater treadmill is used within a veterinarian-directed treatment plan for an individual patient, it is part of veterinary rehabilitation.

The same equipment may also be used for appropriate non-medical canine fitness or conditioning programs.

What should owners expect at ATC?

If underwater treadmill activity is part of a dog's rehabilitation or fitness plan, ATC staff supervise the session and operate the equipment according to that program.

Dogs vary in how quickly they become comfortable with a new environment, so sessions are approached according to the individual dog rather than a fixed expectation.

Does every rehabilitation patient need hydrotherapy?

No.

Underwater treadmill and other aquatic activities are tools available to the rehabilitation team.

Whether they are appropriate depends on the individual patient, evaluation, medical information, and goals of the rehabilitation plan.
