Is it true that when you are talking about a general fact, knowledge, or science you don't use any article (e.g. a, an, the) at all?
For example,
1. Dog is our best friend
2. A dog is our best best friend
3. Dogs are our best friend
Here I am not specifying any particular dog.
I think 1 is the most appropriate. I cannot say 2 and 3 are wrong

The article 'the' can be used, but it sounds old-fashioned
