what is use of builder pattern

Question

Hi

I have tried to implement builder pattern https://www.sololearn.com/en/compiler-playground/cwxSQdBnZgRW

Is this implementation okay? I still have confusion that this pattern solves what problem? What I have done in builder class can be directly done inside the dog class itself.

I think it's supposed to be several builder classes with simplified constructors rather than one builder class with complicated constructor...
