She is way to small to breed
My dog was spayed a month ago at 7 months and she weighed 2.2 pounds at the time of surgery. It is a big deal to have them put to sleep and scarey to. However it would be much worse if she had puppies she would probably have to have a c-section anyhow. I would have her spayed. Not trying to scare you but it is the best interest of the dog
Good luck and enjoy that sweet little dog
