Just like you, your dog knows when someone is speaking your native tongue or a foreign language, Hungarian researchers reported.
Brain scans from 18 dogs showed that some areas of the pups’ brains lit up differently depending on whether the dog was hearing words from a familiar language or a different one, according to a report published in NeuroImage.
“Dogs are really good in the human environment,” said study author Laura Cuaya, a postdoctoral researcher at the Neuroethology of Communication Lab at Eötvös Loránd University in Budapest, Hungary.
Dogs appear to recognize their owners’ native language based on how it sounds overall, since the experiments did not use words the dogs would have been familiar with, Cuaya said in an email.
