MR Dog Tag Who is Mr. Dog Tag? Mr. Dog Tag is my brother Kobie. Kobie was 12 years old when he got his first dog tag machine or Graphotype and started his dog tag business, DogTagsRus.com Over the years my brother has sold 1000’s of dog tags to almost every region of the world. Kobie joined the United States Navy and served as a Navy Corpsman attached to the United States Marines. I have carried on the tradition of selling dog tags and my company is MS DOGTAG. My name is Kelsey. When Kobie got started I was not shy about jumping in and helping. Sometimes I had to get dirty. Most of the time I just had fun !!!
