Loco, there is obviously something very, very wrong for the puppies to have been born that way. If you have any respect for life whatsoever, you need to have both dogs fixed.
The only people who should be breeding are professionals with a serious background in genetics, extremely profound knowledge about their breed, a legitimate background in puppy training, perfect dogs (in character and physiological traits), all of the education necessary to understand and care for the needs of a pregnant mother, and the same for the whelping of puppies.
Did you have your dogs genetically tested? Or are you just guessing? Are your dogs registered with the AKC?
The fact that they're fertile does not mean they should be bred.
If there was a bet out there, I would put all of my cash on the idea that you don't qualify on any of those. If you love chihuahuas, do not put imperfect ones out into the world.
When a person's dog has babies, that person will be morally responsible for each of those puppies, and their puppies' puppies, and their puppies' puppies' puppies and-on-and-on-and-on for the rest of their lives. Ask any professional breeder if their contract requires that every puppy/dog that has come from their dogs to be *returned* to them if the owners decide not to keep them. Was this in your contract? Did you have a contract?
Why do you think there are shelters all over the world where millions upon millions of good dogs have been put down?
What you were doing qualifies you 100% as a backyard breeder.
Do not add to the exponentially growing problem of unwanted dogs.
If you love dogs, go volunteer at your local animal shelter. Have your dogs spayed and neutered. http://www.goodpooch.com/ISSUES/stopbreeding.htm:
"There is a Breeder's Code of Ethics for every breed. Do you plan to follow it? If not, there is a good chance you'll create substandard animals. You'll be harming the breed you claim to love by producing inferior specimens."

"The sad fact is that a phenomenal six million dogs and cats each year die in animal shelters while awaiting homes. There are at least that many more forced to live on the streets with no one to care for their well being. An astounding 30 million dogs and cats are born in this country each year..."
