I have a question.Help me please.

[hoangkha]

- His son and his dog,................. got lost yesterday, have been found by the police.
I make up this sentence to illustrate my question that
What relative pronoun is used in the above sentence?
Thanks in advance.

We'd use 'who'. The boy is rather more significant than the dog.

In real life, we'd be more likely to say, "His son, who got lost while walking his dog yesterday, has been found. He and the dog are alive and well'"

Dear teacher!
Thanks a lot!
But I am taught that
- In defining relative clause, THAT is used when the antecedent includes people and things.
Ex:- The boy and his dog THAT got lost yesterday has been found.
- In non-defining relative clause, THAT isn't used.
Therefore, I am wondering what relative pronoun is used when the antecedent includes people and things in non-defining relative clause.
Best regards!

In your sentence, we have a non-defining relative clause, so 'that' is not an option. We therefore tend to avoid relative clauses in which the relative pronoun refers to both people and things, as I suggested in my first response.

Also, we can use who for animals like pets- if I were talking about my dog, I could say My dog, who went missing yesterday, was found this morning.

To avoid using a relative pronoun in sentences of this kind , I use a participle phrase.
- His son and his dog, getting lost yesterday, have been found by the police.
Is it possiple, teachers?

No, that's not natural at all.

His son and his dog, [both] lost since yesterday, have been found by police.
His son and his dog have been found by police, having been lost yesterday.

His son and his dog have been found by police, having been lost yesterday.

I'd use 'got' rather than 'lost' there. As it stands, it seems to me as if someone mislaid them.

I wasn't quite sure if the son and the dog "got lost" (lost their way) or were lost by someone else!

If they lost their way, then I agree with you that "having got lost yesterday" would be better.
