What Breed Produces the Most Puppies?

If you have a pregnant pooch, you have probably begun wondering the number of puppies will be popping out in a few months.

After all, you have to begin preparing for all those lovable puppies and buying supplies, so it is necessary to know whether to anticipate.

Towards completion of the pregnancy, your vet will likely be able to palpate the mama’s tummy or take an x-ray to identify an “specific” number of pups in her belly (although it can be simple to miss one of the pups, so you’ll never understand for sure until the little wigglers start coming out). But we’ll attempt to discuss the essentials of litter size, so you can begin preparing.

A beautiful exhaustive study of the topic was published in 2011. The scientists examined over 10,000 litters representing 224 types and discovered that the mean (average) litter size in this group was 5.4.

Nevertheless, there’s a reasonable amount of variation at play. Miniature breeds generally produced litters of 3.5 puppies, 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 largest litter ever documented, when she provided 24 pups by means of Caesarian section.

This is undoubtedly rather the abnormality, as the majority of dogs produce much smaller sized litters than this. In reality, Neapolitan mastiff litters generally number between 6 and 10 pups.

A few other notable cases including substantial litters include:

– A Springer Spaniel brought to life 14 puppies in 2009.
– An Irish setter brought to life 15 puppies in 2017 (on Mother’s Day, no less).
– A white German shepherd called Mosha brought to life 17 young puppies in 2015.
– In 2016, a Maremma sheepdog gave birth to 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 gave birth to a litter of 19 puppies.

Aspects Influencing Litter Size

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


A dog’s breed is among the most crucial aspects affecting litter size. Basically, larger types produce larger litters. That’s why Shih Tzus, Pomeranians and Chihuahuas have litters usually varying from one to four puppies, while Cane Corsos, Great Danes, and other giant breeds frequently bring to life 8 pups or more.


Within an offered breed, bigger people generally give birth to bigger litters. For example, a 45-pound Labrador retriever may produce a litter of only 5 or 6 young puppies, while an 85-pound Lab may produce a litter of 10 or more.


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


Dogs in good health are most likely to produce bigger litters, and they’re likewise most likely to produce healthy young puppies. In truth, it is important that any female slated for breeding trials be in perfect health to ensure she and the pups will survive the birth and whelping process.


Diet likely has a strong impact on litter size. Some breeders compete that dogs who are fed a premium commercial food that is supplemented with high-protein foods (such as meat and cheese) produce larger litters than dogs fed low quality foods or those fed just top quality industrial foods (without any extra proteins).

Gene Pool Diversity

The smaller a dog’s gene swimming pool is, the smaller sized her litters will tend to be; conversely, dogs who come from more varied backgrounds tend to have bigger litters. This suggests that dogs from lines that have been inbred extensively will slowly establish smaller sized and smaller sized litters.

Person Genetic Factors

Dogs are all people, who differ in countless ways; often, this can consist of litter size. This is very difficult to anticipate, but dogs who produce large first litters and likely to produce big second and 3rd litters, assuming all other aspects remain constant.

Keep in mind that most of these characteristics associate with the dam (female) rather than the sire (male). Nevertheless, the sire does have some impact on the litter size. His breed, size, health, age and specific hereditary makeup will partially identify the size of the litter he sires.

How Many Litters Can a Dog Produce in a Year?

Some women can produce several litters within a 12-month duration. It just depends on the dog’s natural cycle, body condition and the desires of the breeder. A handful of canines will cycle quickly enough to produce 3 or four litters in a year, however a lot of dogs only have 2 cycles annually, spaced about six months apart.

However, breeding a female twice in the very same year is discredited by lots of breeders. Doing so is very hard on the mom’s body, and lots of think that it will result in a decline in the overall variety of puppies produced by a dog over her lifetime. Accordingly, many will permit their dog to produce a litter, and after that give her a breather throughout her next heat cycle. This essentially indicates that they’ll produce one litter annually.

Nevertheless, other breeders see no reason to avoid reproducing dogs in heat, as long as they are healthy and in good physical condition.

In fact, breeders of this state of mind often argue that because fertility decreases with age and the majority of dogs will be 6 months older with every heat cycle, you can produce more pups over the course of a female’s life by reproducing in back-to-back heat cycles throughout the prime reproductive years of a dog’s life.

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

As previously pointed out, litter size varies based on a number of elements, however for argument’s sake, we’ll presume that she has about five pups in each litter. That means that– again, in theory– a single dog may be physically capable of producing upwards of 70 pups(!) over the course of her life.

However, this would be insanity. Reproducing a dog this often times would probably jeopardize her health, and this type of pedal-to-the-metal breeding is more characteristic of puppy mills and deceitful breeders than conscientious breeders who value the well-being of their pups.

Additionally, some of the registration companies will not permit you to register an unrestricted number of litters. For instance, the Kennel Club of the UK will only permit you to register approximately six litters from a single mother.

What Breed Produces the Most Puppies?

As mentioned earlier, a dog’s size– and therefore her type– is most likely the most essential single factor that influences litter size. Bigger dogs produce bigger litters, so it stands to reason that types with larger average size will produce more puppies than breeds with smaller average body size will.

Basically, Great Danes will generally produce larger litters than Chihuahuas will. We can’t discover a reputable research study that has actually looked for to identify the most fertile type, however it is certainly one of the biggest ones, such as among the mastiffs, Irish wolfhounds, or Great Danes.

However, it is a bit more difficult to identify which type will normally produce the most pups over the female’s whole lifetime. This is partially due to the reality that small dogs routinely live a lot longer than big breeds do. A Pomeranian may, for example, live to be 15 years of age, while Irish wolfhounds normally only live for about half as long.

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

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