I understand that you're a minor and not the culprit in this scenario - my comment is not stating that giving dogs away for adoption is bad; In this case, it sounds like the correct course of action.

My comment was referencing the poor state of care that lead to a purebred dog being left unattended and having an unintentional pregnancy because of this. The fact that this situation occurred is the indicator that your father is likely not a good pick to be a pet owner.
