Transcript for 'Life at Vet U' Shows Vet Students Tackling Animal ER Challenges
If you love animals, you might think being a vettarierinarian is a day job. A new reality show is highlighting the stress of taking care of pets. You can't put out this fire, no matter what you throw at me. Reporter: For America's top vet students. I want to be one of the pest in the world. Reporter: Getting an education isn't a walk in the dog park. If anyone thinking it's easy, they're wrong. Reporter: After three grueling years of cramming and test taking, their fourth year they put their skills to the test with man's best friend and beyond. Animal planet's new reality series follows six students at the university of Pennsylvania just months away from graduation. Is it alive? Reporter: As they try to prove that they have what it takes. Nice work. Saved a life today. It's like getting intoort Knox. Reporter: Rebecca is one of those students. A dog lover. Her passion for pets led her to her career. He's relaxed, sleeps most of the day. Reporter: Look at those eyes. And even helped her dating life. He introduced you to your fiance? Reporter: I had 60 pounds of dog food and the management lady was like that kid is single and he really wants to help you carry your dog food. We were dating ever since. Reporter: But becoming a vet takes a lot more than just a love of animals. It's time and labor intensive. How grueling is the process? Words can't describe. You have no life outside of school. You have to make an effort to give yourself a break. We spend eight hours a day in class, and then another five or six studying after. Reporter: Do you think for the most part people have no idea of all it takes to picture a veterinarian. I think most people have no idea. We have the exact same things for animals as more humans. We have dermatologists and kadologists, on kogss. You name it, we have it. We do everything that if do you go to the emergency you get done. He's like why am I in here? Reporter: We head back to the emergency room where Rebecca who chose a small animal specialty, spent much of her time honing her skills. She's going to do her initial examination. Reporter: We meet a nervous pupall pup puppy, who has been vomiting. We're making sure his eyes are okay, his heart is okay, his lungs are okay. Reporter: Rebecca sees similar cases in the show. How old is he. Reporter: 20 weeks. Sounds like he's vomiting everything up. Reporter: Another young dog came in at the tail end of her shift. The dedication it takes to be an animal doctor often means you can never just clock out. Of course I take the case and will do anything for him. But that means a lot of extra hours. Whatever has been making him vomit isn't going to need surgery. It's just going to need a little bit of time. He probably ate something that didn't agree with him, and now he has a tummy ache. Reporter: The dog isn't giving much. Humans say it hurts and they're like where? He's not going to tell me that. Reporter: I had a grandfather who said if something is wrong with me, take me to a vet. They figure out what's wrong with you. I equate it to being a pediatrician. Your patients don't talk. The only thing you have the what the owners say and your physical exam findings. Honestly, I would rather go to a vet than a doctor too. Reporter: And there's more variety when it come to animals. Over at the new center, professors like Dr. Veen teach their students how to take on the challenges that come with with treating larger animals. We're a large animal hospital. I do a lot with horses. We treat goat, sheep, cow, pig, you name it, we've seen it. Reporter: Some of their past patients, elite athletes. It can be intimidating. And exotic animals like this zebra with arthritis. That one looks pretty close. That looks better. That looks good. Reporter: Today he's helping a horse who pulled up lame, who manages to stay pretty calm, but when his half ton patients get unruly, things can get dangerous fast. Make a mistake with a dog or cat, you get bit, and it can be nasty. Make a mistake with a large animal, and it could be deadly. Can I look in your mouth? Reporter: Lindsey was one of his students. Her temperature is 102.7. You have to learn about every species. It's all about taking whatever learning experiences there are and applying them to how it's best going to help you. Reporter: Assisting him with C sections on cows. One thing I love is that you can be in one procedure in the morning and then suddenly you're pull good another procedure. Your technique for large animals matters. There's always the chance for things to go haywire. All hands on deck. A C section on a calf when you're taking a 100 pound calf is not a one human job. It takes a lot of physical strength. You have to pull the baby calf out of the mother. You're a big boy. It's one thing to study something. It is quite another to get in there and actually do it yourself. To feel what it's like, and to feel the strength that you need to do it. Same thing on the bottom side. He's great with how much he lets us do and get in there and experience it. Reporter: For these vets, getting here was worth autotoil and sacrifice. Do you love what you do? 100%. There's not a day that goes by that I'm not so happy with my choice. Reporter: For "Nightline," I'm linsey Davis in Philadelphia. Vet U premiers this Saturday on animal planet.
