Dogs are able to distinguish their names from other words, even when spoken in different tones of voice. However, they also respond to the tone of their owner's voice, regardless of what words are being said.
Studies have shown that dogs' brains light up in different ways when they hear their own names being spoken compared to other words. This suggests that they have a special neural pathway for processing their own names. In addition, dogs are more likely to respond to their names when they are spoken in a positive tone of voice. This is because dogs associate positive tones of voice with rewards such as treats or praise. Over time, they learn that responding to their names is a good thing to do and can result in them being rewarded. As a result, the combination of their name being spoken in a positive tone of voice is effective at getting their attention .
