When does a Shih-tzu stop having puppies?

Shih Tzus, like other dogs, can stop having puppies when they reach menopause. This usually occurs between 6-8 years old but can vary depending on the individual dog.

However, it's important to note that menopause doesn't mean a dog is infertile. A Shih Tzu can still have puppies after menopause, though it becomes less likely as they age.

Here are some additional details:

* Spaying is the most reliable way to prevent a Shih Tzu from having puppies. Spaying involves removing the ovaries and uterus, permanently eliminating the ability to get pregnant.

* Signs of menopause in dogs can include irregular heat cycles, decreased fertility, and changes in behavior.

* Consult a veterinarian for advice on when to spay your Shih Tzu and for any concerns about their reproductive health.

Remember, it's crucial to make responsible decisions regarding breeding and to consult with a vet to ensure the health and well-being of your dog.
