[quote=“rousseau”]As a former ESL teacher long repatriated to an English-speaking land, allow me to chime in: neither option in the poll is conventional.
The two conventionally acceptable responses are:
- Yes, there is one
though the first response, in some contexts, would be considered somewhat evasive by the enquirer should said enquirer eventually learn that there was indeed only one dog in the room. So, the best response would be number 2.
Having said that, if there were multiple dogs in the room then “Yes, there are” would be conventional. And if the question were “Is there a dog in the room?” then “Yes, there is” would be conventional. In addition, if the question were “Is there a dog in the room?” and there were five dogs, then the correct answer would be “Yes, there are several.”
Anyway, there would be some clarification.
“Yup. One,” would be good.
