tag question with exclamation mark.how should it be written?is there to be comma there? it's a dog!, isn' it?

Question

which is correct? it's a dog!, isn' it? it's a dog! isn' it? im suspicious about if there's to be comma after exclamation mark. thanx in advance.

Answer 1

Grammatically speaking, an exclaimation point never appears in the middle of a sentence unless it's in quotation marks. Example "It's a dog!" he exclaimed.

And even then there's no comma after the exclaimation point. And if you're writing how you talk, then the more correct way, would be without the comma.

Timi m has the grammatically correct way...

Answer 2

"It's a dog, isn't it?!"
