Study: Large dogs are smarter than small

"Does brain size matter? Yes, at least when it comes to dogs, according to new american research."

"the Bigger dogs, with bigger brains, are in some ways smarter than the smaller ones. According to a new study from the university of Arizona. It is mainly when it comes to cognitive ability, short-term memory and self-control as the smaller dogs will be outclassed. But what can it be?"

"– No one is quite sure yet, but we are interested to find out, " says Daniel Horschler, who led the study, in a press release."

"Brain size turned out not to have any significance when measured the dogs' social intelligence. It means that the study shows similar results as previous studies of primates: larger brain means better cognitive ability."

"– We thought that dogs are very good to examine, because the size of the brain varies, so. It is everything between the chihuahua and the great dane, " says Daniel Horschler."

"the Training played no role"

"the Study is based on over 7 000 dogs of 74 different breeds. Among other things, as to test short-term memory by hiding dog treats under one of the two up and down -- you agree the plastic cups. Self-control was tested by placing the candies in front of the dog but at the same time prohibit it from eating."

"the Scientists took into account whether the dogs were trained or not. But no matter how well trained the pets were, so did the bigger dogs better."
