There are several questions here that disturbs me. I won't be trying to help. Having a dog carries responsibilities. Female dog owners are particularly responsible to either spay the dog by 6 months or educate themselves to avoid the irresponsible breeding that leads to the misery of unwanted dogs. Millions of dogs are slaughtered every year at great expense for lack of homes. How can you live with yourself for contributing to this tragedy? If you must keep an intact female dog, at least get some books and educate yourself. Check www.akc.org for their discussion of responsibly breeding. Check www.petfinders.org to se how many dogs in your area need homes.
And yes having an unneutered male without good cause is irresponsible, more so if you fail to control it.
