Typical range: 6 to 10 puppies · large breed
- C-section risk
- low
- Best way to know
- An X-ray after day 50 counts the puppies.
An average is not a prediction. First litters, older dams and the sire all change the number.
Read the Golden Retriever pregnancy guideLitter size by breed size
Borge et al. (2011) analyzed 10,810 litters across 224 breeds. Larger breeds tend to have bigger litters, with an overall mean of about 5.4 puppies.
| Size group | Examples | Typical litter |
|---|---|---|
| Toy | Chihuahua, Pomeranian, Yorkie | about 3–4 |
| Small | French Bulldog, Dachshund, Shih Tzu | about 4–5 |
| Medium | Beagle, Border Collie, Husky | about 5–6 |
| Large | Labrador, Golden Retriever, German Shepherd | about 6–8 |
| Giant | Great Dane, Mastiff, Saint Bernard | about 8 or more |
What changes litter size
- Breed and body size. The strongest factor.
- Age of the dam. Litters tend to be smaller in young first-time mothers and in older dogs.
- The sire and the timing of mating. Mating at the right time in her cycle affects how many eggs are fertilized.
- Health and nutrition. A well-conditioned dam is more likely to carry a healthy litter.
Questions
Frequently asked questions
How many puppies will my dog have?
It depends mainly on breed size. Toy breeds average about 3 to 4, medium breeds about 5 to 6 and giant breeds 8 or more. Only an X-ray taken after about day 50 gives the actual number.
Is the first litter smaller?
Often, yes. First litters and litters from older dams tend to be smaller, but there is a lot of individual variation.
Can an ultrasound count the puppies?
Not reliably. The uterine horns coil and overlap, so puppies are easily double-counted or missed. An X-ray after day 50 is the standard way to count.
Why does the count matter?
Knowing the number tells you when she has finished whelping, so a retained puppy is not missed.
