I think when you use dr or dr's (with or without the period) as an abbreviation for doctor, it's fine if used in an informal setting. After all, you are abbreviating the word doctor in a generic. 争议处理后续： （1）判决、裁决执行 （2）和解协议、调解协议执行 3、业务能力要求 做dr入门不难，但要把dr做好挺难的，中国可能不乏优秀的诉讼仲裁律师，但优秀的争议解决律师不.

Recently, i was reading articles on the net and realised that there is a lot of ambiguity over the usage of dr. I usually prefer the dot while writing. Dr.是doctor的简写，即博士（最高学位。 且必须是取得该头衔后才能称呼。 在读博士是 doctoral candidate）。 by the way：博士后不是学位的一种，只是在某处工作的博士的类职称而已。.
