Master! It's me. You're right there. I can feel it. (companion dog)

- Chuchu? Is that you? (dog's master)
--------------------------------
The master of the dog found the missing dog after a long time. In this dialogue, do we have to use 'that' alone? How about the following?

1. Is it you?
2. Is this you?

Yes, you could use any of those pronouns.

In the dialogue you provided, where the dog's master is trying to figure out if the companion dog in question is indeed Chuchu, there are different ways you could phrase the question. Let's examine each possibility:

1. "Is it you?" - This question is grammatically correct and also commonly used. The pronoun "it" generally refers to something previously mentioned or something already understood. In this case, "it" would be used if the dog's name, Chuchu, was mentioned earlier in the conversation. For example, if the dog's name was mentioned just before this question, the dog's master could ask, "Is it you?" However, if the dog's name hasn't been mentioned previously, using "it" might be less common and could potentially lead to confusion.

2. "Is this you?" - This question is also grammatically correct and commonly used. The pronoun "this" is used to refer to something nearby, typically physically close to the speaker. In this case, "this" could be used if the dog's master is pointing or gesturing towards the dog. By saying "Is this you?" the dog's master is indicating that they are referring to the dog in close proximity.

Both "Is it you?" and "Is this you?" are acceptable ways to ask the question in the given context. The choice between them depends on factors like whether the dog's name has been mentioned earlier and the physical proximity of the dog to the speaker.
