When one thinks about reproducing an animal,there are many obvious questions to consider.Is the dog of sound temperment ? Is it an excellent representative of the  breed ,true to the standard.Is it in excellent health ? Some less obvious questions to consider before breeding your beloved  chihuahua (or any breed for that matter) are below.
DO. I know which health problems are specific to my breed ?Has the Bitch  or stud been checked for inherited conditions?

Can i accept the loss of my bitch to have this litter?(Complications can and do happen and bitches do die during and after whelping.)

Will i find the best male possible to complement my bitch,even if it means paying a high stud fee and traveling to find him ?

Have I educated myself about whelping and raising puppies so that i will recognize a problem before it is to late ? After the female is pregnant is really not the time to be doing it .

Can i take off work for several days around the bitches due date so she won't be left unattended at whelping?

Do i  enough extra money to cover the cost of a C-section if it is required ? ($200-$1000  ((or more)depending on your area)

Do i have the ability to take a few weeks off work to raise the litter should anything happen to the dam ?Can i afford up to $100.00 a week for milk replacer (depending on the breed )if the dam has no milk?

Can i afford to feed a litter of weaned growing pups until they are all sold ? ANd do you have a plan of what you will be doing with the ones that do not sell ... It can  happen you   know ..

Can i afford to  vaccinate the pups during the time they are in my care until they are sold  ?

Do I expect to profit from the sale of these puppies (most litters cost breeders money ).If you are lucky you may break even after all the pups are sold.

How selective will I be in finding homes for the puppies? What  criteria will new owners have to meet?(do they have a fenced yard,Can they afford routine medical care,will they be able to afford veterinary bills if an emergency should arise,can they afford a good quality dog food  etc.)

Will i take back any unwanted puppies or dogs when the owner no longer wants them  our cant keep them?

Can i afford AKC registration fees ?

Do i enjoy cleaning up after a litter of puppies and will i do it with the health and well being of the dogs in mind even when i have worked all day and have had no time for myself ?

Can i live with the fact that should i lose my bitch  during whelping,that the breeding was by my own choosing ?

Please do not breed your dog if you can't answer YES to all of the  above Questions!

Please leave the breeding of Chihuahua's to the professional  chihuahua breeders !!

STOP! Think before you  breed ! IF you cannot  even think of losing your female then do not breed as giving birth can have complication in this tiny breed.
