my dog Fresca, every morning, goes to the bottom of the deck steps in our backyard and stares intently at the far corner of the yard for a few seconds. then, when she spost the squirrels she's looking for, she takes off at breakneck speed to try and grab one. she goes fast enough she has to hit the fence wit the side of her body to slow down. but she hasn't got one yet. eventually though either the squirrels are gonna slow down, or get distracted, or fresca is gonna speed up, or get lucky. either way she's gonna get a squirrel one day. because this is a dog that grabs birds out of midair that fly above her. well used to fly above her.
