Dogs are special. Every dog owner knows that. And most dog owners feel their dog understands every word they say and every move they make. Research over the last two decades shows dogs really can understand human communication in ways no other species can. But a new study confirms that if you want to train your new puppy, you should be speaking to it in a certain way to maximise the chances that it follows what you’re saying.
There is already quite a lot of research evidence showing that the way we communicate to dogs is different from the way we communicate to other humans. When we talk to dogs, we use what is called “dog directed speech”. This means we change the structure of our sentences, shortening and simplifying them. We also tend to speak with a higher pitch in our voices. We also do this when we are not sure we are understood or when talking to very young infants.
A new study has shown we use an even higher pitch when talking to puppies, and that this tactic really does help the animals to pay attention more. The research, published in the journal Proceedings of the Royal Society B, showed that talking to puppies using dog-directed speech makes them react and attend more to their human instructor than regular speech.
To test this, the researchers use so-called “play back” experiments. They made recordings of humans repeating the phrase “Hi! Hello cutie! Who’s a good boy? Come here! Good boy! Yes! Come here sweetie pie! What a good boy!”. Each time, the speaker was asked to look at photos of either puppies, adult dogs, old dogs or at no photos. Analysing the recordings showed the volunteers did change how they spoke to different aged dogs.
The researchers then played the recordings back to several puppies and adult dogs and recorded the animals’ behaviour in response. They found the puppies responded more strongly to the recordings made while the speakers looked at pictures of dogs (the dog-directed speech).
The study didn’t find the same effect applied for adult dogs. But other studies that recorded dogs’ reactions to the human voice in live interactions, including work I have done, have suggested dog-directed speech can be useful for communicating with canines of any age.
