Every time you come home from work, your dog comes running towards you and you tell it: “who’s a good boy” “did you miss me?” ” do you want a treat?” hoping that your doggo will understand. Unfortunately, according to a study done by the Eotvos Lorand University in Budapest, your dog doesn’t understand other words than the ones learned during training. For example, your dog can recognize a sound that will trigger a part of its brain to execute an action, but it won’t understand complex phrases.
