1) You didn't answer my question as to what you're feeding him;
2) I don't know what "peeing out the back of his dick" means. Most dog dicks I've seen only have a front
{Does he have a hole in it or something?}
3) No, you can't freeze his balls; you can only start collecting him now.
4) In order to provide help, you have to actually answer the questions you're asked ... so what, exactly, are you feeding him?
