Study: Dogs as smart as young children

If you think your dog is smart, you're probably right.

A study out of the University of Florida finds dogs have the developmental abilities of a 2-year-old. Researchers say the average canine is capable of learning the meaning of 165 words.

And a different study found dogs can interpret body language and behavior and use it to their advantage. Researchers found dogs are more likely to beg for food from someone who is paying attention to them.
