Hydro trainers for dogs do not require any special legal training. However, there are various further education, training and certification courses that can be taken to acquire knowledge and skills in this field. For example, such trainings are offered by specialized dog schools, animal physiotherapists or experienced aquafitness 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.
