Because the Chihuahua is the smallest dog breed in the world, breeding a Chihuahua differs than breeding other, larger dogs. It is also very different than breeding other toy dogs such as the Pomeranian or Toy Poodle.
If you are thinking of breeding your Chihuahua to produce top quality pups, think this over again. It takes only a very few male stud dogs to breed, but a larger number of female dogs if you are to have your own program.
In most cases, only top winning Champion male dogs are considered to possess the high level of quality needed to qualify as a registered stud. If your female dog is not registered, an honest breeder would not allow a planned pairing to take place. Therefore, you would want to begin with an AKC, high quality female.
The Chihuahua is prone to needing to have a Cesarean. This can be quite expensive and it can compromise the health
of the dog.
You must have all needed supplies, you must have time (breeders spend countless nights awake, hand feeding little puppies that cannot get milk from the dam and without constant nutrients would quickly develop Hypoglycemia), possibly dealing with post-pregnancy health issues for the dam, and you must have dedication, whether breeding one litter or wanting to become a professional breeder.
This, undoubtedly, is not the easiest purebred to breed. Size alone creates obstacles. Health to both dam and pups must be the first and more important goal.
The proper age
to start breeding a Chihuahua female is 2 years minimum with 3 years old being preferred. Some sources will state 1 or 1.5 years, however at that young age, the Chi is not yet fully grown. One of the crucial elements for a safe pregnancy and delivery is for the pelvic region and hip width to be fully formed and at maximum width. Young Chi's also do not have strong enough knee and hip formation, which is so important for carrying extra weight
should be retired by the age of 6 (at the very most) or at any age before this if the veterinarian suggests so. Having a female Chihuahua assessed for breeding capability should be done before any planned pairing. There are a host of medical reasons why a Chi should be retired early from breeding, including stress on various areas (back, knees, hips) and a history of difficult deliveries.
, the proper age is at least 1 year old. The age at which sperm starts to be produced by male dogs is 7 to 8 months and giving a leeway until the age of 1, ensures the sperm strong enough to reach the female's eggs. Studs are in their prime from the age of 1.5 to 5 years old. After this time, the sperm will gradually weaken. While an un-neutered, senior
male dog can technically still impregnate a female, the chances decline as the dog matures.
