Fake dog balls are called Neuticles. They were created by Greg Miller, who was part of the Canine Testicular Implantation Project (CTI). This project included a team of veterinarians who began the development of the surgical procedure and the Neuticles product line. Over the years, people have called Neuticles by many names - prosthetic testicular implants and prosthesis for neutered dogs. Some even call them 'fake dog balls'. But the fact remains, that Neuticles have one purpose - to give your furry pal his looks and confidence back.
