My chihuahua just had one puppy?

That's unusual! While it's not unheard of, it's rare for a chihuahua to have only one puppy.

Here's why:

* Litter size: Chihuahuas usually have litters of 2-4 puppies, with some rare cases having up to 6.

* Multiple births: Dogs, like most mammals, are designed to have multiple offspring.

* Pregnancy complications: Sometimes, issues like a small uterine horn or a health problem in the mother can lead to a smaller litter.

What to do:

1. Contact your veterinarian: It's crucial to schedule an appointment with your vet to ensure both the mother and puppy are healthy.

2. Monitor the mother: Observe her closely for signs of distress or infection.

3. Puppy care: Ensure the puppy is receiving proper nourishment, warmth, and hygiene.

It's important to remember that only a veterinarian can properly diagnose and address any potential issues. Don't hesitate to seek professional help if you're concerned.
