The Guinness World Record for the largest litter is 24 puppies. They were born in Cambridgeshire in 2004.
The largest litter of puppies ever born is currently recorded at 24. In 2009, A Neapolitan Mastiff named Tia broke the Guinness world record by giving birth to 15 male puppies and 9 female puppies.
The average number of puppies in a litter is six to eight, but some large breed dogs have been known to give birth to many, many more! Smaller breeds may have two to five puppies. Dogs that only have one or two puppies may not go into labor on their own and may require a c-section.
Unity, a three-year-old German Shepherd guide dog mum, has given birth to 16 puppies, setting a new record in Guide Dogs' 60-year-old breeding programme.
A typical litter size tends to vary from 1–12 puppies, with 5 to 6 pups being average across all dogs. However, large breeds can have up to 15 pups.
The breed of dog is the biggest determinant of litter size. Generally, big dogs have larger litters because, biologically, they're able to safely carry more puppies.
There are no litter limits and breeding dogs can legally be bred from their first season 6-9 months (as long as they are 'physically mature, fit, healthy') until they cannot physically produce any more puppies. Cruel back-to-back breeding allowed. Legal to kill dogs that are no longer required by the puppy farmer.
While a dog can technically have has many as 30 litters over their lifetime, it's best to keep this number to no more than three or four litters, as over breeding and breeding too often can stress a female out and affect the health of the litter.
It is estimated that the mortality rate is around 20-30% of "live-born pedigree puppies" in the first three weeks of life.
A best practice is 4-6 litters per dog
Most reputable breeders will cap even their fittest, best mothers at around 4-6 litters so that she can be spayed while she is still young and at her healthiest.
Type of semen used – site of insemination
In general, litter size is increased with any type of semen if it is deposited directly into the uterus; in a Scandinavian study, litter size averaged 4.0 pups for vaginal insemination compared to 5.4 pups with intrauterine insemination.
Furthermore, the temperament was affected by litter size and season of birth. One possible interpretation of this would be that it could be possible to affect adult behaviour of dogs by adjusting litter sizes and birth times, but the present data do not allow this conclusion.
According to some dog breeding experts, you should stay away from a dam's first litter. The idea behind this argument is that the first litter is somewhat of a gamble. You practically have no idea how the puppies are going to turn out. After all, the female dog (dam) has never given birth to kids of her own before.
Generally speaking, puppies inherit their size from their parents. If you know how big mom and dad are, you'll have a good idea of how big your puppy will be. This is a good place to start if you're trying to estimate your puppy's future size.
Usually, the size of a dog litter is mainly based on the dog's body size — simply because biologically, bigger bodies are able to carry a larger litter size than smaller bodies. The litter size also depends on the breed of the female. Some small dog breeds will only bear one puppy at a time; we call these singletons.
In mammals, the male determines the sex of an offspring, while the female determines the size of a litter by the number of eggs she drops that become fertilized.
Professional trainers like myself recommend against bringing home two puppies around the same age, let alone two from the same litter. While this sounds like a good plan in theory, in practice it often causes quite a bit of heartache and potentially some serious aggression trouble.
Once the puppies are about three weeks old, they will begin to move around on their own. This is when you can begin to pet them and interact with them more. You should only touch or pick up a newborn puppy if you observe that it is sick, if the mother abandons it, or in the case of orphaned puppies.
If your dog only had one puppy and it died, you should let the mother take her time, clean the spot and then visit the vet. The same rules apply to the vet examination and burial/cremation when it's only a single puppy born. However, the single puppy syndrome is a very rare occasion indeed.
First, when you look at the reproductive and nursing cycle of a dog and their healing needs, it's fairly comparable to a human having a baby every 2 years or so.
Even though most dogs can get pregnant between six and twelve months, this doesn't mean that it's best for the dog. The dog must be matured before getting pregnant and breeding, as it can lead to some behavioral or physical problems. Your dog should have a chance to grow up.

A normal dog gestation period (or pregnancy) is 63 to 65 days, regardless of the size or breed of the dog.
Recreational breeders do not need to register with their local council as a Domestic Animal Business (DAB) or comply with the Code. Instead, recreational breeders are required to comply with their organisation's rules and code of ethics.
RSPCA Australia considers the minimum acceptable age for a puppy to be removed from the mother dog for adoption or purchase to be 8 weeks of age.
If the result is that selling the puppies is classed as a hobby then you will not need to report the income to the ATO.
