WILL MARK BRAINLIEST Read this excerpt from "Are Dogs Dum?" by Karen Hopkin.

And how come we think dogs are so smart? Sure a dog might be clever enough to fetch his leash when he wants to go out. But the same mutt might also bark at a vacuum cleaner and spend a whole hour chasing his own tail. Is Rover really any brighter than a hamster, a chicken, or that kid who's always eating Play-Doh? How can you measure an animal's brain power?
