Dominance Issue?

[Catamount1]

I have a 12 week old, male, Siberian Huskey. He is very energetic and we take him outside for walks and playtime multiple times a day. We took him to the vet last weekend. She had said one of his testicles dropped. A little before we knew that happenedSince, he started ignoring his bite inhibition trainig. We have taught hit sit, stay and come as well as "let's go". He's good at listening when not too excited.

What my question is, is tha he's going back to being bitey. How is
Is the best way to inhibit bit behavior? Plus are his changing hormones playing a role in his more defiant behavior.

The other thing is that he is used to train puppy pads, but just recently, jhe just pees on anything hr likes wherever he likes. The strangest thing was that he crawled ońto op me and then jus
T stood on top of me and pee'd onme

Bite inhibition isn't a one time training thing. It is something you have to continue to stay on top of. When he bites say "ouch" in a high pitch, loud voice and stop playing with him. If that still doesn't work, when he bites do it again but walk away. Give treats and praise when you can successfully put your hands in his mouth, on the toys, in the food, during play without nipping. You have to reinforce the good behaviour so he knows what is expected of him.

Move is pee pads closer to the door and start encouraging him to go outside to pee. If he doesn't know how to ask, teach him. Whether it be by whining, barking, or ringing a bell. Whatever to get your attention. Encourage peeing outside and keep everything off the floor until he has successful started using the washroom outside. But, don't put anything on the floor for a while. This may mean keeping him out of your bedroom/laundry room/basement but making sure he doesn't have accidents is just as much your responsibility.

Do you have a yard?  Do you use a crate?  Does he have the run of your home?  Sounds like maybe not enough structure.  He may be peeing out of excitement. Assume an UTI would have been caught by the Vet.
Hiw okd was he when you got him?
Nipping discouraged with a firm No bite!  easy and praise when he stops.  This is normal puppy behavior and he is a puppy.  He needs structure, limititation if space and patience and consistency.  
Keep an eye on the testickes to make sure both drop.
Look up NILF training for dogs.
He is going to be too large a breed to use puppy pads soon.
