Hydro fitness trainers for dogs do not need any special legal training. However, there are various continuing education courses, trainings and certifications that they can complete to acquire knowledge and skills in this field. For example, these trainings are offered by specialized dog schools, animal physiotherapists or experienced aqua trainers. It is important that the canine hydrotherapist has a good knowledge of canine anatomy, physiology and biomechanics, as well as experience working with dogs in water.
