GMAT Verbal Section | relative pronoun doubt

Below is a sentence from an exercise in foundations of GMAT verbal book.

I am supposed to find all the pronouns and antecedents in below sentence:

It is clear that the dog loves the new toy that Joey bought for it, so much so that Joey is glad he didn't spend the money on himself.

Isn't 'that' (bold one) a relative pronoun whose antecedent is 'new toy'?
The solution only lists it, it, he, himself as pronouns..

Can someone clarify? Thanks.
