Just as the other person said in their post, 4lbs is generally considered too small for breeding if I am not mistaken. My little girl is almost 9 months and has yet to even reach 4lbs, she is still lingering around the 3lb mark. I think if you don't intend to breed most people have their dogs spayed/neutered. It reduces health risks for the dog. For the bark collar, I would say not to use it. I am someone who is dead set against that, though I can only speak for myself.
You said that yours is active and barks a lot. How often does she get to run around and play? Her behavior can be the result of boredom, and some just need more activity than others. My girl is full of energy and can't get enough attention, she is always wanting to run and play with small naps in between. Sometimes playing with them more or going on daily walks can make all the difference in their behavior.
