Another reason Berns chose not to anesthetize his canine participants is because he says wanted to treat the dogs like people. All the dogs in the study have consent forms signed by their owners, and only positive training methods are used to prepare the animals for the MRI. Berns’ own dog, Callie, was the first dog to have her brain scanned. With the help of a dog trainer, Berns taught Callie to enter an MRI simulator he’d built in his home. Callie learned to enter the tube, place her head in a chin rest and sit still while wearing earmuffs to protect her ears from the machine’s noise. After a few months of training, Callie was ready for her first MRI, and Berns and his colleagues got their first maps of canine brain activity. Other owners soon volunteered their dogs for research, and Berns has now scanned more than a dozen of their brains. The more data he gathers, the more he’s convinced that dogs aren’t that different from us. The canine brain maps showed Berns that dogs use a region of the brain known as the caudate nucleus in a similar way to humans. The caudate has a large number of dopamine receptors that increase in both dogs and humans in response to an anticipated moment. For example, the dogs’ caduate activity increased when they smelled a familiar human or dog or when their owners reappeared after leaving the room. These findings dont necessarily mean that our dogs love us, but because many of the same things activate both the human caudate and the dog caudate, neuroscientists say this could be an indication of canine emotions. “The ability to experience positive emotions, like love and attachment, would mean that dogs have a level of sentience comparable to that of a human child,” Berns writes in the New York Times . “And this ability suggests a rethinking of how we treat dogs.” Because dogs and other animals seem to have emotions similar our own, Berns suggests that we assign a “limited personhood” to animals that shows evidence of emotion. He says we could also take it a step further and give dogs “rights of personhood,” which would provide them with protection against exploitation.

The Dogs Trust charity invited photographer Rankin to turn his lens on some very special pooches, all rehomed by the trust
He lies with me when I do my 15 minutes of physiotherapy each morning, and looking at his handsome, soppy face cheers me up if Im feeling frustrated. Although hes soft, gentle and loving, he can be a bit dim and we call him Donk. Hes always making me laugh, like yesterday when he jumped on the garden table because he was showing off, or when I gave him my red football which he took great delight in shredding. If we shout Heron, Hugo! he runs towards our pond to scare off the birds, but hes getting middle-age spread so he never catches them. Hes like a best friend and brother to me. Hugo has always had joint problems in his legs, so Im careful not to hug him too hard as I dont want to hurt him.
How Do Dogs Learn Words? Just Like Kids (Op-Ed)
A dog learning a thousand words is nothing to sniff at. But what is truly remarkable about Chaser, the border collie who has taken the world by storm, is how she learns words. Chaser makes inferences in a similar way to human children. When Chaser played the game that tested the same ability in the citizen science project Dognition , not surprisingly, she was off the charts. (Can your dog make inferences like Chaser? See the game. ) Besides dogs, dolphins, apes and parrots can also learn an impressive number of words. What is special about children is that if you show a child a red block and a green block, then ask for “the chromium block, not the red block,” most children will give you the green block, despite not knowing that the word ‘chromium’ can refer to a shade of green. The child inferred the name of the object.
