Now, prepare yourself for a dosage of cuteness that may exceed your doctor's recommendation. Dr. Besser is standing by with a defibrillator. These are cheetah cubs playing with a puppy. I don't think people at home realize how cute this is. It's not a stunt. It's all happening at the dallas zoo. There's an important reason to have a puppy growing up alongside these cats. Abc's aditi roy has more. Good morning, aditi. Reporter: Good morning, dan and bianna. These cu are precious. Not only for how they look. But the fact they're also endangered. Only 7,000 grown cheetahs are raised. It's important to officials that the baby cubs have a smooth transition into adulthood. These adorable balls of fluff are the newest attraction at the dallas zoo. 8-week-old male cheetahs are brothers. It's play, eat and then sleep. And not necessarily in that order. Reporter: And they are about to get an unlikely playmate. An 8-week-old black labrador retriever. There's no danger for amani. He's 14 pounds. Almost twice as big as these guys right now. We're going to socialize them in a way that when they're two years, they're going to have that established relationship. It's a slow process. Just getting to know each other. They'll be together 24/7. And they'll really forge a relationships just like the two cheetah siblings are. They're almost about to go to sleep. Reporter: They're cute and cuddly now. As all three grow, sharing the same room, they're going to start noticing some big differences. Cheetahs are expected to go to three feet long and weigh 140 pounds. Eight months from now, the cheetahs will be running, 50, 60 miles per hour. And it's going to be great to have a dog that can show them how to run and chase and do all those things that we want those animals to do because that's a natural behavior. Reporter: The cubs are part of the zoo's animal adventures outreach program, to teach the public about highly endangered species. There's less than 10,000 cheetahs in the wild. Hopefully this education is about learning more through books, the internet, how they can help wild life. That's really what we're all about. Reporter: The world's fastest land animals. They can go from 0 to 60 in three seconds. And amani means peace in swahili. Hopefully his name will live up to it. Thank you very much.
