Your girl is exhibiting the classic signs of a false pregnancy. I had a foster dog I took in with a false pregnancy last year, and she was exactly the same way. The aggression toward your Maltese is because of the hormone imbalance. The girl I had was vicious, but sweet and calm after the "pregnancy" was over. My girl ate a lot, gained weight, had big nipples, and her milk came in. She gathered stuffed toys, and bit her previous owner's child when the little girl tried to pick up the toy. My vet would not spay until she finished the pregnancy.
