Can anybody call themselves an Animal Osteopath?
It is unfortunate, but anybody can call themselves an Animal Osteopath, or practitioner of any sort, including Massage Therapy, even if they have had no training, no background in healthcare or even worked with animals! There are no regulations in place to protect animals from malpractice. It is VERY important that you check into the qualifications and experience of any practitioner working on your horse or pet.
