* Breed: Some breeds are known for having larger litters than others.
* Age: First-time mothers often have smaller litters than dogs who have given birth before.
* Overall health: A dog's health can influence litter size.
* Genetics: Just like humans, dogs inherit traits, and litter size can be influenced by genetics.
Generally speaking, a first-time mother dog could have anywhere from 1 to 12 puppies in her litter. It's a big range!
If you're curious about a specific breed, you can do some research online or talk to a veterinarian.
