What Causes Single Puppy Syndrome?
To let you have a detailed insight into the reasons stated behind Single Puppy Syndromes, here are the concepts behind each believed rationales have been deciphered.
The breed of the dogs is the leading reason that influences a female dog to have just one pup. This means if the dog comes from a bigger-sized dog breed such as the German Shepherd, Labrador, Huskies, etc. it will give birth to 8-10 pups at one time.
On the contrary, small-sized toy breed dogs such as Scottish Terrier, Chihuahua, Pomeranian, etc. tend to give birth to a single pup sometimes. Because of their small breeds, these dogs especially the Scottish Terrier are scapegoats of the Single Puppy Syndrome.
Age Of The Mother Dog:
Dogs tend to stay fertile until he/she passes away but the fertility of a female dog drops down after the age of 5-7. This means if the mother dog has passed the 5 years to 7 years old mark, gradually her capability of carrying more offspring will begin to decrease.
Thereby, she can give birth to just one puppy at one birth time.
Health Of The Mother Dog:
The health of the mother dog is directly proportionate to the size of its litter as well.
Healthier mother dogs are capable of carrying healthier and more offspring at one time. However, a weak and unhealthy mother dog might not be able to carry and give birth to 3-4 puppies at one birth time as her body will not support nurturing more than one puppy.
Genes are the next factor that heavily influences the quantity of offspring in a litter. But unfortunately, it’s difficult to anticipate whether a mother dog’s genes will affect the birth of one pup in a litter or not.
However, if you notice that a mother dog has given birth to a single puppy twice or thrice in a row, just know that she is developed as a mom of singletons.
The degree of inbreeding has also an equal impact on the size of the litter. The more breeders going to inbred a litter, the smaller the number of puppies going to be in the future.
Because inbreeding is a path for departing deleterious alleles as well as it entrenches a high span of health problems in dogs that don’t allow to carry more puppies.
Is It Possible Or Rare For A Dog To Only Have One Puppy?
It’s considered a quite rare incident for a mother dog to give birth to only one puppy at one time.
It’s because dogs fall in the category of polytocous species of animals which means dogs are capable of carrying and giving birth to more than two puppies in one birth time. And their standard litter size ranges from 3 to 7 puppies depending on dogs’ breeds.
Therefore, when only a single pup is born of a dog, it’s deemed unusual. Also, know that the chance of a single puppy pregnancy is just about 6.4% which confirms Single Puppy Syndrome a rare case among dogs.
Are Singleton Puppies Bad?

And all of these causes clear that singleton puppies are kind of accepted as bad.
Do Singleton Puppies Survive?
If the size and position of singleton puppies inside the dog mom’s uterus are in favor of being born naturally, the chances of the puppy’s surviving are higher and it’s about 85%.
However, if a C-section has taken place to give birth to the singleton puppies due to the pup being bigger sized and the mother dog having difficulties with normal delivery, the puppy may or may not survive. Statistics say, only 42% of puppies have survived after a C-section.

What Can I Do With A Singleton Puppy?
After getting a singleton puppy, you must make sure to provide him with all the convenience and an environment that the pup didn’t get in the first two to three months of its life.

But it would be better if you could borrow foster litter regardless of its breed to foster your singleton puppy. But if you can’t do any of this, be his parent and take care of the pup as its mother would do.
Single Puppy Syndrome causes a dog to give birth to only one offspring. This syndrome is mainly caused by the breed of the mother dog. Then the age and health of the mother dog, the genetics of the mother dog, and inbreeding are also equally responsible for a dog having only one puppy.
