The cutest tiny puppy is actually two years old and fully grown, although nobody believes it.

Don't skip this post because we will share with you a cute one-year-old Cavalier King Charles Spaniel puppy that will certainly fill your heart with a little bit of joy.

We have a Cavalier King Charles Spaniel puppy taking over the internet because he's so sweet and adorable. This cute puppy is named Nessa. Despite being two years old and full-grown, Nessa looks like a pup even though he is already fully grown. The little Nessa weighs just seven pounds (3 kilograms), whereas most cavalier dogs weigh between 13 and 18 pounds. Thankfully, being tiny does not mean he has any problems. The puppy is still healthy and happy, and he adores his owners so much.

The cavaliers have a good relationship with children and other animals, even though they're aristocrats. However, although they are friendly, they require a great deal of human interaction.
