How many young are usually born in a canine litter?

Canine litters typically consist of about four to six young, though the exact number varies significantly depending on the species and breed.1

For example, the gray wolf generally produces a litter of five or six pups. In contrast, domestic dogs show variation based on size: small-breed dogs, such as a terrier, often have small litters of two or three puppies, while large-breed litters can contain as many as 10 to 12.23

The Arctic fox stands out among carnivores for having the largest litters, which average about 11 young but can sometimes reach 20 or more. Regardless of the species, these young are born after a gestation period that typically ranges from 51 to 80 days.1
