PHILADELPHIA (CBS) — A best-selling expert in canine behavior will be in North Philadelphia on Thursday evening for a free talk.
Dr. Alexandra Horowitz in the author of Inside of a Dog.
“There are something like 75 million dogs in the US today, and I think they’ve almost outpaced the number of households that have children,” she tells KYW Newsradio. “So they’ve become a part of our family.”
But Horowitz, who runs the Dog Cognition Lab at Barnard College in New York, says even though humans have lived with dogs for tens of thousands of years, we can’t assume we know everything about them.
Horowitz says the best way to learn about dogs is to look at their behavior. Ever wonder why your dog spends so much time smelling something you can’t see?
“They are olfactory creatures, so their primary sense is smell, not sight,” explains Horowitz. “They have hundreds of millions of receptors in their nose that can detect smells. They can get information about individuals, about their health, about how long ago somebody walked by — about all sorts of things that are invisible to us.”
