Ok. So i guess i wasn't to clear I the which dog is which. I have two Chihuahua which themselves are not related, one ( the male ) from a breeder that i did a small project for while the other (the female) was paid for from another person all together. I did take them in for testing due to the female had me concerned from what i thought to be a defect. It was not though. The testing said that both are in good health but the male could possibly have a hip issue later in life. Now these two i own and have had 4 litters in 6 yrs. No i don't intend to have them fixed and i DONOT consider myself a breeder either.
Now the dogs i was concerned about are the puppies from my dogs. They are two litters apart. Male is older than female and no i have not had them tested in anyway. Most i do with the pups is get them their shots and send them on their way. I don't breed to sell but when we have a litter its typically due to ppl, coworkers, friends and family asking for a pup.
I will admit that I'm not by any means a breeder nor do i broadcast to ppl that i am.
This situation does have me flustered because i told my mother to keep her dog in the room while it was in heat and she had the brother there.
When my dogs have had pups it was planned, except the first litter total accident, after learning the females cycle we can plan for the most part.
So the female (sister) is not showing yet. Is it possible she may not be pregnant?
