What is the critical risk if a Sheepadoodle puppy spends its first three months exclusively with one person?

Answer

The initial bond can become exceptionally strong, sometimes manifesting as mild separation anxiety when that person leaves

Intense, early one-on-one time can inadvertently train the dog to expect exclusivity, leading to dependency issues when the favorite person is absent.
