Dogs, however, were adept in using human cues to find food, it said.
Experienced New Zealand dog trainer and Dog Obedience Committee chairwoman Rosemary Cleator said the results were pleasing but not out of leftfield.
"It doesn't surprise me that dogs could do it, but it does surprise me that they were better than chimpanzees who are supposed to be more intelligent, theoretically.
"But I think I'd say that dogs' main communication is body language and the more we learn and train with them, the more we realise that they follow the very slightest body cues."
Ms Cleator was sceptical of the suggestion that dogs have adapted over time to develop a better understanding of human cues.
"Certainly there is more understanding that dogs go by body cues. Whether that means that dogs have got better, or whether that means that people have got better, I'm not quite sure. Years ago you never considered the use of your body to get them to do things."
Ms Cleator said some dog owners would welcome the favourable results, but didn't see the report making any difference when training dogs.
