One plus two equals WOOF!

Dogs, it turns out, are a lot smarter than you thought. Unless you’re a dog, that is. In which case you probably figured you were clever all along. Researchers say they’ve found canines can perform rudimentary math and “speak” by modifying their barks situationally. Not surprisingly, the math trick was discovered using food treats. Shortchange Fido on a Scooby snack and he just knows. Regarding their speaking ability, dogs usually use high-pitched single barks when separated from their owners and a lower, harsher superbark when strangers approach, say the researchers. Playful woofs are high-pitched and unevenly spaced.
