What article if any should I use in the sentences below?

I have -/a/the dog Rex.
I have -/a/the brother Sam. 

I surmise that in the second case there is no need for an article. Thank you for your help in advance!

In I have Rex or I have Sam, you don't use articles.

If you're using the word "dog" or "brother", you must use articles.

"I have a brother, Sam" means you have a brother called Sam (or that you are speaking to someone called Sam and telling him that you have a brother).

"I have a dog, Rex" means you have a dog called Rex.

"I have the dog, Rex" means that you have a particular dog that you probably expect the other person to have heard about previously, and that it's called Rex.
