Dug, the dog, is easily distracted by ... squirrels (well, he's easily distracted by everything, but especially squirrels). He can be talking (yeah, it's Pixar/Disney so the dog talks) & right in the middle of the sentence, he shouts, Squirrel!. Then he carries on with whatever he's talking about.
Why do squirrels twitch their tails? Squirrels will twitch their tail for many different reasons. They  twitch their tails when they are scared, mad, uneasy, or a predator  is in the area.
