How would you react if you came across an English-speaking canine with impeccable grammar? We don't think it's going to happen, but it would surely freak us out!

Comedian and voice actor Rudi Rok, however, can produce a perfect bark and sound just like a real dog. He filmed a very funny video showing how the animals reacted towards him.

Salli, a Norwegian breed, was the first one up. The canine barked back at first. But after Rok barked several times, the dog got scared and walked away.

The furry Torsti came next. The black poodle fiercely returned the barks and showed no signs of backing down — proving that poodles are brave and smart despite their cute appearance.

Noah, who has features of a shepherd, got scared and sat down — an unexpected reaction from such a huge creature coming from a tough breed.

Another small dog, Nino, circled the barker. However, the pug got too scared and ran away.

Large and furry Tuutikki observed and synced his barks with Rok. Like singers in a choir, the two had a barking duet. 

Black Terrier Elsa sat still without any reaction.\
