Society when you wanna get your pets spayed or neutered; Doctor, I'd like to get my dog neutered. I'm sorry but I can't do that until he is at least 6 months of age. Doing it at a too early age can cause hormone problems that affect the development of their bones. Society when you wanna get your child transitioned; Doctor, I wanna get my child transitioned. Ok, I'll prescribe puberty blockers for him and would you like top or bottom surgery?
