Hi, chrisjack. Our dog had to have hydrotherapy after a bad cruciate ligament injury, in order to re-build the muscle strength and, just as critical, give him back the confidence he had lost in using his leg.
He'd never been near water that deep or in such a strange environment, but he was
dropped into the (Circular) pool with a safety harness attached to a centrally-mounted overhead frame, which allowed the dog to swim in a circular fashion.
It seemed a bit alarming to us at first, but it was actually a very controlled environment, and the man knew exactly what he was doing. The dog immediately began to swim like mad, using all four legs. He also thoroughly enjoyed himself, so much so that when we went back a week later for the next session, he was excited with anticipation. He quickly got back to using the leg after the therapy. I can heartily recommend it!
All we needed to take with us was a towel and a brush, any other needs were catered for by the facility itself. I don;t know where you are based but the place we went to was inear Ashford in Kent. Details are on the attached link:

Hope this helps:
