A video of little girl named Noa playing with her doctor's kit while checking a dog is making rounds on the Internet.

The adorable little girl pretends to be a veterinarian, while her father, Manuel Ruiz, catches the moment on video. The family's dog was extremely well behaved despite what the girl is doing to him.

Bull terrier Neckar looks like a willing patient for the checkup. First, Noa gives him a vaccination by pretending to inject the dog's legs. Then she stands up to look inside the dog's ears. After that, she uses her stethoscope to try to listen to Neckar's heartbeat. The dog just sits still while the checkup routine is being done.

Good dog indeed! Neckar is the most patient patient of all the dogs in Noa's "clinic," noted the Dodo.

He is, no doubt, a very tolerant dog.

The video of the future veterinarian has already garnered more than 5 million views because of this very sweet moment. Seems like the two have a close friendship since the dog, apparently, trusts the little girl and didn't even try to run away!
