Which one of these is correct? Oxford Comma

[Triostar]

Can you let me know which is correct?

A) Rolo is a happy dog, and can often be found with his owner.

B) Rolo is a happy dog and can often be found with his owner.

C)Rolo is a fun, happy dog, and can often be found with his owner.

D) Rolo is a fun, happy dog and can often be found with his owner.

E)Rolo is a fun, happy, playful dog, and can often be found with his owner.

Which are correct?
Have I used an Oxford comma? And if so, why?

I think:

Maybe in C or E because in it is in a list of 3 but also I have a noun in the middle of the list (dog)

No to A because it is only a list of 2 things. If so, is the comma correct?

Or do none use the Oxford Comma?

Thanks.

None of these is an Oxford comma. The Oxford comma is an optional comma used after the penultimate item in a list of several things, e.g. 'a dog, a cat, and a rabbit'. It's not used much and some people think it's incorrect.

None of your examples should have a comma before the 'and'. You would put a comma if it were separating two independent clauses which would be able to function as sentences on their own if you removed the 'and'. Example: 'The waiter brought the soup, and the woman ate it straight away'.

This doesn't apply to your examples, because there is no subject of the verb in the second clause (because it's the same noun doing the verb in the second clause as in the first clause, unlike in my example. So your 'Can often be found with his owner' doesn't make sense on its own.

I think they're all correct as they are, although for preference in D would either put a comma after dog (as in C), or would change 'and' to 'who' - 'a fun, happy dog who...'.

E has an Oxford comma, surely?

I'd say E

All are wrong. The correct statement is

F) Rolo is a tasty chocolate treat.

 @WuTangGran

D is how we were taught at school and how I’ve always written

B and D are both correct. The Oxford comma is best used for disambiguating information eg:

The Wise Men saw Mary, Joseph, and the babe lying in the manger.

Same

D is correct. An Oxford comma is not needed in that sentence as there is no ambiguity.

Yes. After ‘soup’ there could be a full stop and no ‘and’ therefore creating two separate sentences

E has an Oxford comma, surely?

No, it would have an Oxford comma if there were an 'and' before the word 'playful'. The comma before 'and can' is not an Oxford comma because it's (unnecessarily and incorrectly) dividing two clauses, not dividing items in a list.

What @Fairislefandango said.

Thats great, thanks for all the replies....

No worries. I love explaining stuff like this <weirdo>. Luckily I'm a languages teacher, so I get to do it a lot, though my audience isn't always grateful like you are, OP

Ah yes. Had to scroll back.
