LENS is widely used with domesticated animals. There is a practitioner in Marin CA who specialized in using LENS with horses. I have treated a few cats and dogs, usually with noticeable results. If you pet is struggling, it is worthwhile to try LENS with them.
What is notable about using LENS with animals is that it negates the possibility of a placebo effect from the treatment, as it is unlikely that an animal would grasp what is happening to them. Therefore observed better self regulation in animals after LENS treatment (eating/grooming/socialization behaviors) is a strong indication of the efficacy of the modality.
