getting my puppy fixed ?

theres bad points to BOTH sides. read up and decide for YOURSELF.

 

These people want his balls cut off as soon as possible because your dog isn't a real american pitbull terrier. No offense, I'm sure your dog is a wonderful dog. ( Got any pics?)
With that said you need to let him reach his full adult hood before doing that, he will not reach his full potential.
The idea of a blue pit is terrible because its not good for the breed, breeding just for color is hardly a good idea. This breed of dog is meant for a purpose, not to be the color blue. I'm sure you are just uneducated about the history but your obviously a fan of the breed and if educated you will just appreciate the game breed apbt even that much more. Enjoy your dog, like I said im sure hes a great dog. Not knocking him at all. Don't chop his balls off til hes adult, really I wouldn't ever do it. Just be responsible and keep him from running the streets, this breed doesn't need to be running loose anyway, to misunderstood and too much drive.
