4 month old pit won't bark (he is a pitbull terrier mix)?

He is still just a puppy. Why do you WANT him to bark?? Be glad that he doesn't or your next question would be " how do I stop my dog from barking"

What do you mean he bits?

Aggressively or playfully?

Aggressive behavior is NEVER ok. Especially with a bully breed. If its aggressive you need to stop this right now! As for the barking my pit bull does not bark much either. Every dog has is own personality. Pits don't usually bark very much unless they need to. Consider this lucky! They don't make good guard dogs, but are wonderful pets! Much so silly to be guard dogs...

Yeah I think that puppies bark for a while, until he is a little older. My aunts puppy didn't until he was a little older.

he to young or maybe theres nothing to bark at how could you have him neutered would you like it if someone cut your balls off >:(

your lucky i have a pit and it wont stop barking your the lucky one and no nuetering has nothing to do with his barker

he is still young, give him time, then you will say how can i stop him from barking?

Wait a while he's still young.
