Hudson Aquatic’s AquaPaws series was designed to improve the lives of canines and small animals by offering low-impact, high-resistance therapy or workouts for rehabilitation from injury, optimal training and conditioning, and weight loss. The AquaPaws and AquaPools K9 provide the natural properties of water (buoyancy, resistance and hydrostatic pressure) for a rigorous cardiovascular workout with reduced impact and stress on joints. Just compare the features below and choose the series that best fits your needs. Contact Us for more information.

The AquaPaws Plus system includes additional features to the AquaPaws. It provides a larger touch-screen control panel with 500 programmable treatments, an energy saving mode as well as an auto-clean system, where the unit cleans itself under the treadmill belt.


The latest unit in the AquaPaws underwater treadmill line, this system offers a lower entry threshold, magnetic door, a larger running surface, larger windows and holds up to 30” of water to accommodate larger breeds. The treadmill also offers adjustable speeds and several optional features to enhance patient outcomes.

An entry level modular version of the AquaPaws system, the AquaPawsJR was developed to offer a smaller footprint alternative. It offers all the basic options along with a smaller chassis and the convenience of mobility. It can easily be installed, disassembled and moved.

This system is the top-selling water treadmill for canines. It provides a low-impact treadmill workout to help increase muscle strength and endurance without the damaging effects of land based exercise. AquaPaws is perfect for animals that require rehabilitation, suffer from obesity, have arthritis, or need a safer, quicker option for fitness and conditioning.

Hudson Aquatic’s freestanding fiberglass canine pools are designed in a variety of sizes with options like spa jets and resistant swim currents to provide animals with a complete workout. AquaPools K9 is perfect for gentle swimming during rehabilitation or high-energy splashing and playing with pool toys for fitness or recreation.

“The AquaPaws has made a huge difference for every aspect of my practice.
I can offer a productive treatment for conditions that I would have had no options
to treat before. The patients, clients and techs really enjoy working with the
AquaPaws; it’s often fun for everyone. It adds a new dimension to my medical
practice and has significantly added to profits as well.”


“We currently have two of the Hudson units in one of our facilities, and are
placing a third one in a satellite clinic in the following week. At Wizard of Paws
Physical Rehabilitation for Animals, LLC., we see between 20 and 30 patients per day
and our units are kept busy! The underwater treadmills in the main clinic are often
busy 12 hours per day, and are able to vary with both conditioning to neurological clients.
We have been very pleased with the durability of the product, the quality and the excellent service.
In my almost 16 years of experience in canine physical rehabilitation, I would absolutely
recommend Hudson, and will continue to use their products in future clinics"


"We love the positive outcomes that we are able to achieve at The PawStand with
our AquaPAWS Plus system. The jets are great for resistance training with our fitness canines,
and our rehab dogs respond quickly whether they are being seen for a
musculoskeletal injury or a neurological condition."
