Weird that people are so concerned about dogs feeling manly about themselves. Last I checked, we don't have foreskin implants for dudes that have been circumcised.
For those of you silly enough to consider purchasing these things, fear not about offending your dog's manhood. There are 4 anatomically correct varieties - rigid firmness, natural firmness, UltraPlus and UltraPLUS with Epididymis (if you're going for that walrus look).

The only thing worse than Neuticles? Neuticle apparel for the jerkoffs that support stupid inventions.
Adding this to my Christmas wishlist...

Next on this company's agenda: ear implants for dogs with droopy ears. Seriously.
