Dogs’ brains are sensitive to the familiar high-pitched “cute” voice tone that adult humans, especially women, use to talk to babies, according to a new study.
The research, published recently in the journal Communications Biology, found “exciting similarities” between infant and dog brains during the processing of speech with such a high-pitched tone feature.
Humans tend to speak with a specific speech style characterised by exaggerated prosody, or patterns of stress and intonation in a language, when communicating with individuals having limited language competence.
Such speech has previously been found to be very important for the healthy cognitive, social and language development of children, who are also tuned to such a high-pitched voice.
But researchers, including those from the Eötvös Loránd University in Hungary, hoped to assess whether dog brains are also sensitive to this way of communication.
In the study, conscious family dogs were made to listen to dog, infant and adult-directed speech recorded from 12 women and men in real-life interactions.
As the dogs listened, their brain activities were measured using a functional magnetic resonance imaging (fMRI) scan.
The study found the sound-processing regions of the dogs’ brains responded more to dog- and infant-directed than adult-directed speech.
This marked the first neurological evidence that dog brains are tuned to speech directed specifically at them.
“Studying how dog brains process dog-directed speech is exciting, because it can help us understand how exaggerated prosody contributes to efficient speech processing in a nonhuman species skilled at relying on different speech cues,” explained Anna Gergely, co-first author of the study.
Scientists also found dog- and infant-directed speech sensitivity of dog brains was more pronounced when the speakers were women, and was affected by voice pitch and its variation.
These findings suggest the way we speak to dogs matters, and that their brain is specifically sensitive to the higher-pitched voice tone typical to the female voice.
“Remarkably, the voice tone patterns characterizing women’s dog-directed speech are not typically used in dog-dog communication – our results may thus serve evidence for a neural preference that dogs developed during their domestication,” said Anna Gábor, co-first author of the study.
“Dog brains’ increased sensitivity to dog-directed speech spoken by women specifically may be due to the fact that women more often speak to dogs with exaggerated prosody than men,” Dr Gabor said.
14-Year-Old Dog Trembles With Fear After Being Surrendered to Shelter By Owner
Dogs would never abandon their humans – even when they get old. Sadly, the same cannot be said of humans when it comes to senior pets.
Thankfully there are superheroes, also known as animal rescuers, who take in the unwanted dogs and give them the love and care they deserve.
Rochelle Steffen is the founder of Mac’s Mission, a special needs dog rescue based in Jackson, Missouri. The small nonprofit rescues dogs nationwide that would otherwise be euthanized. Many are neonatal puppies with cleft palates or hydrocephalus as well as senior dogs like Lindt.
The 14-year-old dog was surrendered to a shelter by her owner who stated she couldn’t keep her because she was moving to an apartment. The senior dog is beyond heartbroken and frightened by her new surroundings.
Mac’s Mission took her in and renamed her Lindt – she was previously called Butterscotch. Rochelle posted a video of Lindt on TikTok that brought many to tears. She wrote, “Lindt is so shut down. She is 14 and has just been ripped away from everything she’s EVER known. You should really get a plan in place for your dog.”
Countless people took to the comments to say that they would never abandon their dog. Sadly, this happens far too often. Rochelle replied by saying, “This woman said the same thing and now she’s moving into an apartment. She also severely neglected this dog.”
Lindt arrived with overgrown nails, covered in flea, and a large tumor hanging off her stomach. She had her nails trimmed, received a warm bath, and had surgery to remove the tumor. The rescue posted, “This is what you guys help support. This is the 20th dog we have rescued in just a few days. And we can’t rescue anymore until we win $1 million, adopt some of these out, or foster some of these out. Thank you for letting us save this precious girl and she will be available for adoption when she is finished getting vetted.”
Lindt’s sad story has touched the hearts of many dog lovers. Several commented that they have a plan in place in case something should happen to them to ensure their dog is cared for and doesn’t end up at a shelter.
One dog owner wrote, “I literally have a plan played out in my will for my pup — including who she should go to, how to pay for it, who needs to visit, etc — she’s my child.”
Another suggested people should start assigning godparents to their dogs.
Lindt deserves to live her golden years in a loving home. People near and far are encouraged to adopt as the rescue only asks that people come to the shelter to finalize the adoption. They will happily set up meet and greets but only with approved adopters as they are not open to the public. Anyone interested in adopting can fill out their online application here.
Mac’s Mission’s federally trademarked slogan “i am pitbull strong” refers the rescue dog named Mac who inspired the rescue. Rochelle adopted the pit bull on April 11, 2011 and had ten glorious years with him before he crossed the Rainbow Bridge. “His superhero legacy will live forever in the ripple effect of this special needs rescue,” wrote Rochelle.
