Hola Yvonne
I imagine you are referring to this sentence:
Tú no quieres que te regale un perro. (You don't want me to give you a dog.)
In Spanish, we literally say "You don't want that [I] give you a dog", but that would be incorrect in English. This happens with all sentences saying "I want you, him, her, them +to do something".
Hope this helps.
Saludos
Inma
