SERIOUSLY, if you and your family don't know when dog is in heat, you DON'T need to be breeding. period. Breeding any animal needs to be left to professional, experienced, dedicated people. Have your Chi's been shown and titled? Have they been tested for health diseases? Does your Dad know that there are already countless Chi's dying in shelters... not to mention millions of other breeds? And, what if your Chi needs an emergency c-section, or her uterus becomes infected shortly afterwards... or, the very likely occurance that she does not nurse her puppies, leaving your family up at all hours of the day/night to bottlefeed newborns? That is $1000's right there, and you are risking her life and newborn puppies lives. And for what? A few dollars? You could easily spend way more on caring for her and her litter than you will get from her pups... especially since Chi's often have just 1 puppy.

please reconsider!
