What is Hydrotherapy?
Hydrotherapy is defined as “the use of exercises in a pool as part of treatment for conditions such as arthritis or partial paralysis.” The concept has been around for around 2,500 years for humans but wasn’t formally introduced as an alternative treatment until the 18th century and then in the 19th century, it became more widely known. Horses in the horse racing industry were the first animals to be introduced to hydrotherapy. When it came to canines, it was used in Greyhound racing after seeing the benefits in the horses. It wasn’t too long before it became available for dogs of the general population
Hydrotherapy with underwater treadmill work essentially allows for rehabilitation and exercise by taking the weight off of the compromised joints and allowing movement that would otherwise be painful or impossible. The viscosity of the water actually increases the work that the muscles are doing at the same time. There are three main types of hydrotherapy for dogs:

What Are the Types of Hydrotherapy?
Pool-based Hydrotherapy
A dog is put into a life jacket that has a handle on top for the therapist during a pool-based hydrotherapy session. The therapist holds the dog up and lets them swim while holding them up in the water. They may also let the dog swim on their own depending on their strength. This can be done in either a normal pool or a dedicated hydrotherapy tub.

Underwater Treadmill
This is probably what comes to mind when you think of hydrotherapy for dogs. Essentially, there’s a treadmill belt in a small tank of water that’s filled with warm water which can be adjusted. The dog is assisted by the therapist as they walk on the treadmill or may be harnessed in. This form of hydrotherapy is extremely customizable for what’s needed for each dog.

Whirlpool Therapy
Whirlpool therapy is like a jacuzzi for dogs that help to relieve pain from health disorders or surgery. Dogs are lowered into the whirlpool via a harness and the water level is adjusted. A warm jet stream then massages the injured muscles.

What Dogs Can Do Hydrotherapy?
Not all dogs qualify for hydrotherapy and there needs to be written veterinary consent before beginning hydrotherapy and the therapist will also examine the dog to determine if they qualify. The following can disqualify a dog for hydrotherapy time being or indefinitely:
- External fixator
- Skin irritation or infection
- Diarrhea
- Untreated cardiac, liver or kidney disease
- Incontinence
- Uncontrolled epilepsy
- Emesis
- Unhealed surgical incisions
Dogs of all ages with various disorders or injuries can benefit from hydrotherapy. Hydrotherapy should only be conducted by a professional to diminish the risk factors. Remember to never force a dog to swim, if they are showing signs of discomfort, discontinue hydrotherapy immediately for either the time being or until the therapist feels they are able to continue.
