Dialogue:  Norman: Hey, neighbor. How's it going?  Shawn: Fine. How about you?  Norman: Okay. Huh, by the way, my wife and I are going out of town this weekend, and I was wondering if you could take care of some of our animals while we're gone. You know our dog, Jaws, don't you?  Shawn: Yeah. My leg still hurts from the last incident.  Norman: Hey, he's just a playful little beast.  Shawn: Right.  Norman: Hey, he likes to bark a little, and his bark is worse than his bite.  Shawn: Oh yeah.  Norman: Just feed him a can of dog food a day, and make sure he has plenty of water in his dish. [Oh] And then, take him for a walk around the block.  Shawn: Well, how about if I just throw a Frisbee over the fence to give him some exercise? Wouldn't that work?  Norman: Ah, and then, he likes to watch the 3:00 soap opera on Channel 4 [What?] ... and brush his teeth after you give you some doggie treats around 4:00.  Shawn: Man, you really pamper your dog.  Norman: And, then brush his fur for about twenty minutes. He tends to shed this time of year. [Ah, what?] And then scratch him around the ears. Otherwise, he feels neglected.  Shawn: Is that it?  Norman: Well, and then there's Claws.  Shawn: Claws? Who's Claws.  Norman: Oh, he's the cat we adopted from the animal shelter, but he's a little temperamental.  Shawn: What do you mean "temperamental"?  Norman: Well, he has mood swings [Mood swings?], but he's been doing better since he's been going to the animal therapist.  Shawn: A therapist?  Norman: So, be sure to feed him a half cup of cat food two times a day [What? A therapist ...], and don't forget to put out (on) some soft classical music during his nap time at 2:40 p.m. But don't let him out of the house because he might run away and chase the neighbor's dog.  Shawn: You have some high-maintenance animals.  Norman: Not really. And, don't forget to change the cat litter daily, or he might have an accident on the carpet. [Oh, great.] And finally, there's Buttercup.  Shawn: Buttercup? Who's Buttercu ...? I'm afraid to ask.  Norman:...  Question: What is one of Shawn's concern about the dog?   - It can be somewhat aggressive.  - It eats too much food at one time.  - The dog might mess on his carpet.
A:
It can be somewhat aggressive.
