Yes, your little girl is too small to breed. At that size she would likely need a c-section, and there is a possibility you could lose her. An unaltered females chances of getting mammary cancer and uterine infections (which can also lead to death) increases with each heat cycle that goes by and she is not spayed.
Bark collars should never be used. There are other methods to work with a dog to keep them from barking. I would suggest an "obedience class", they are helpful and fun for your dog and you.
