Why pekingese dog doesn't get along with a puppy?

Pekingese dogs are known for their strong personalities and can be territorial, which might lead to conflicts with a playful and energetic puppy. The Pekingese may perceive the puppy’s energy as overwhelming or intrusive, causing stress or aggression. Additionally, their more laid-back nature might clash with the puppy's exuberance, making it challenging for them to coexist peacefully. Proper introductions and gradual socialization can help ease tensions between the two.
