There are 2 forms in English for giving something (the direct object) to someone (the indirect object).
This is the more formal form:
I give the ball to Snoopy.
I give it to Snoopy.
I give it to him.
This is the more casual form:
I give Snoopy the ball.
I give him the ball.
X I give him it. < -- we don't use a pronoun for the direct object in this form.
