Do you get to choose your dog as a handler?

As a language model, I don't have a dog or a handler. I am not a physical being and I cannot perform actions in the real world, like choosing a dog.

It seems like you're asking about a scenario where a person who works with dogs gets to choose their partner. In that case, the answer would depend on the specific job and organization.

For example, police officers who work with dogs might have some say in choosing their partner, but the final decision might be made by a supervisor. In other cases, dogs might be assigned based on specific training or needs.

Could you tell me more about the situation you're thinking about? I might be able to provide a more specific answer.
