How Many Puppies Can Dogs Have?

If you have a pregnant pooch, you have probably started questioning how many pups will be popping out in a few months.

After all, you need to begin preparing for all those cute puppies and buying products, so it is essential to know whether to expect.

Towards the end of the pregnancy, your veterinarian will likely be able to palpate the mother’s belly or take an x-ray to figure out an “precise” variety of pups in her tummy (although it can be simple to miss out on among the puppies, so you’ll never ever understand for sure till the little wigglers begin coming out). However we’ll attempt to describe the essentials of litter size, so you can start preparing.

A beautiful exhaustive research study of the subject was released in 2011. The researchers evaluated over 10,000 litters representing 224 types and found that the mean (average) litter size in this group was 5.4.

However, there’s a fair quantity of variation at play. Mini types usually produced litters of 3.5 pups, while big breeds usually produced 7.1 young puppies per litter.

What’s the Largest Litter Ever Recorded?
In 2004, a Neapolitan mastiff called Tia ended up being the mom of the biggest litter ever documented, when she delivered 24 young puppies through Caesarian area.

This is undoubtedly quite the anomaly, as most dogs produce much smaller sized litters than this. In fact, Neapolitan mastiff litters normally number between 6 and 10 young puppies.

A couple of other notable cases including big litters include:

– A Springer Spaniel brought to life 14 puppies in 2009.
– An Irish setter brought to life 15 young puppies in 2017 (on Mother’s Day, no less).
– A white German shepherd named Mosha gave birth to 17 puppies in 2015.
– In 2016, a Maremma sheepdog brought to life a litter of 17– which set the California state record for litter size.
– A bullmastiff produced a litter of 23 pups in 2014.
– In 2014, a 3-year-old Great Dane brought to life a litter of 19 young puppies.

Factors Influencing Litter Size

There are a number of various things that can affect the size of a dog’s litter, and we’ve detailed a few of the most crucial ones below. It is challenging to empirically figure out how much these different aspects influence litter size, and it is likely that the numerous aspects affect each other to some degree.


A dog’s breed is among the most crucial factors affecting litter size. Put simply, bigger types produce bigger litters. That’s why Shih Tzus, Pomeranians and Chihuahuas have litters normally varying from one to 4 pups, while Cane Corsos, Great Danes, and other giant types often bring to life 8 pups or more.


Within a provided breed, bigger people normally give birth to bigger litters. For example, a 45-pound Labrador retriever may produce a litter of only five or six pups, while an 85-pound Lab might produce a litter of 10 or more.


While dogs typically remain fertile for their entire lives, they are most fecund throughout early the adult years– typically in between 2 and 5 years of age. Nevertheless, a dog’s first litter is generally smaller than subsequent litters.


Dogs in good health are more likely to produce larger litters, and they’re also most likely to produce healthy pups. In fact, it is important that any female slated for breeding trials be in perfect health to ensure she and the puppies will make it through the birth and whelping process.

Diet likely has a strong impact on litter size. Some breeders contend that dogs who are fed a high-quality commercial food that is supplemented with high-protein foods (such as meat and cheese) produce larger litters than dogs fed second-rate foods or those fed only high-quality industrial foods (with no extra proteins).

Gene Pool Diversity

The smaller sized a dog’s gene swimming pool is, the smaller sized her litters will tend to be; on the other hand, dogs who come from more diverse backgrounds tend to have bigger litters. This suggests that dogs from lines that have actually been inbred thoroughly will gradually develop smaller and smaller litters.

Individual Genetic Factors

Dogs are all individuals, who vary in numerous ways; in some cases, this can include litter size. This is very challenging to forecast, but dogs who produce large first litters and most likely to produce big 2nd and third litters, assuming all other elements stay consistent.

Note that the majority of these characteristics relate to the dam (female) rather than the sire (male). However, the sire does have some impact on the litter size. His type, size, health, age and individual hereditary makeup will partially identify the size of the litter he sires.

The Number Of Litters Can a Dog Produce in a Year?

Some females can produce numerous litters within a 12-month period. It just depends upon the dog’s natural cycle, body condition and the desires of the breeder. A handful of dogs will cycle rapidly enough to produce 3 or four litters in a year, however a lot of dogs just have 2 cycles each year, spaced about 6 months apart? states Pet Health website.

However, reproducing a female twice in the very same year is discredited by many breeders. Doing so is very difficult on the mom’s body, and numerous think that it will lead to a decrease in the overall number of young puppies produced by a dog over her lifetime. Accordingly, many will allow their dog to produce a litter, and then provide her a breather throughout her next heat cycle. This essentially suggests that they’ll produce one litter annually.

However, other breeders see no factor to avoid breeding dogs in heat, as long as they are healthy and in good physical condition.

In truth, breeders of this state of mind often argue that since fertility decreases with age and most dogs will be six months older with every heat cycle, you can produce more pups throughout a female’s life by reproducing in back-to-back heat cycles during the prime reproductive years of a dog’s life.

How Many Litters or Puppies Can a Dog Produce in Her Lifetime?
Theoretically, a single female dog might produce many litters in her life time. Assuming that a female produced two litters each year starting at 1 year of age and continued doing so up until she was 8 years of age, she ‘d produce 14 litters over her lifetime.

As formerly discussed, litter size varies based upon a variety of aspects, however for argument’s sake, we’ll presume that she has about five puppies in each litter. That indicates that– again, in theory– a single dog may be physically capable of producing upwards of 70 puppies(!) throughout her life.

Nevertheless, this would be insanity. Breeding a dog this many times would likely jeopardize her health, and this type of pedal-to-the-metal breeding is more particular of young puppy mills and unethical breeders than conscientious breeders who value the wellness of their puppies.

Furthermore, a few of the registration organizations will not allow you to register an unlimited variety of litters. For example, the Kennel Club of the UK will just permit you to register up to six litters from a single mother.

What Breed Produces the Most Puppies?

As pointed out previously, a dog’s size– and for that reason her breed– is probably the most crucial single aspect that influences litter size. Bigger dogs produce bigger litters, so it stands to reason that types with larger typical size will produce more puppies than types with smaller typical body size will.

Put simply, Great Danes will generally produce bigger litters than Chihuahuas will. We can’t find a reliable research study that has looked for to identify the most fertile breed, but it is undoubtedly among the largest ones, such as one of the mastiffs, Irish wolfhounds, or Great Danes.

Nevertheless, it is a bit more difficult to figure out which type will generally produce the most puppies over the female’s whole life time. This is partly due to the truth that small dogs routinely live a lot longer than large types do. A Pomeranian may, for example, live to be 15 years of age, while Irish wolfhounds generally only live for about half as long.

So, while the Pomeranian’s litters are likely to be much smaller sized than those of a wolfhound, the Pomeranian will have the chance to produce much more litters over the course of her life.

Additionally, small types tend to experience their first heat at a younger age than larger breeds do (in some cases a whole year earlier). They likewise tend to cycle faster, which likewise makes them most likely to produce more litters than bigger breeds.
