🐶 Dog Lifespan: Everything You Need to Know

A dog’s lifespan can vary widely depending on size, breed, genetics, and care. Here’s a clear breakdown to help you understand what to expect.

⏳ Average Dog Lifespan

Most dogs live 10–13 years, but many live longer with good care.

🧬 Lifespan by Breed (Examples)

• Chihuahua: 14–18 years

❤️ Factors That Affect Lifespan
