From Chihuahuas to Great Danes: Are Dog Brains the Same?

October 8th, 2010 by Marghi Merzenich

Person to person, the human brain varies a little in size and shape–but not dramatically so. After all, adult human skulls are all roughly the same size and shape.

But what about dogs? Does a chihuahua’s tiny skull hold the same kind of brain power as all that can fit inside a mastiff’s  giant noggin? Does the flatness of a pug’s skull affect its brain? In other words, has the development of wildly different dog breeds created different types of dog brains?

Apparently, it’s not a widely studied topic, but here’s one recent study that finds some fairly significant differences. Dog lovers, enjoy this scientific peek into your best friend’s brain!

    Although there may be physical differences in the canine brain, years of dog training and interaction have taught me that our canine friends are very similar to each other in basic instinctive behaviour.

    That said, some are most definitely more clever than others!!
