Given the task definition and input, reply with output. In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: The film begins 4 years after the events of the first one, with George Banks telling the audience he is ready for the empty nest he'll shortly receive with all of his children grown up. Shortly thereafter, Annie tells the family that she's pregnant, and George begins to mildly panic, insisting he is too young to be a grandfather. He has his assistant make a list of people who are older than him, dyes his hair brown, and decides he and Nina should sell the home their children have grown up in if one more thing goes wrong with it.
Termites strike the house two weeks later. George puts the house on the market without telling Nina, and sells it to the Habibs. At dinner, after a discussion on whether the baby's last name will be hyphenated or not, George reveals the house has been sold. Nina is livid, as she and George have to be out in 10 days and have no place to go. Having no place to go, the Banks stay at the mansion owned by Bryan's parents. As the MacKenzies are on a cruise in the Caribbean, the Banks have to deal with their vicious Dobermans, much to the chagrin of George, who is still obviously paranoid from a previous mishap with them. Nina begins experiencing symptoms that bring up the concern of menopause. After visiting the doctor the following day, they are given the opposite news: Nina is pregnant, too. 
Not long after, they have a chance meeting with Franck, Annie's wedding planner, who is elated at both women expecting. George switches gears, now believing he is too old to be a father again. His feelings come to a head when he and Nina go to Annie's and Bryan's house to announce their news. Nina brings his insensitivity to light and tells him not to come home. As an apology, George reluctantly hires Franck to do the baby shower. As they are driving home, Nina and George have differing perspectives on the prospect of becoming new parents again. Both express how strange it will be, but begin to welcome the change.
What is the last name of the family that owns the dogs that George is scared of?
