Today for the first time He bit us and apparently My GF said somethign came out of his mouth on her arm that smelled bad... i didnt see it And dont know where it came from but she thinks his mouth... he is 8 months old, Could it be hormones like he just wants to mate? Hes never done this before, Help has this happened to anyone

It's certainly not his hormones, rather a bit of old food.

Piggies can bite if they are frightened.
