Tiny Chihuahua Treats His Sister Like a Racetrack as She Stares Straight Into the Camera

Luna has found her spot on the rug, and she's keeping it. Sitting square in front of the bookshelf, the little gray dog fixes her eyes on the camera while her brother Dooby, a white Chihuahua, does laps around her. Every lap brings his tail along for the ride, flicking past her nose, curling under her chin and brushing across her cheek like a feather duster.

The face is what makes it. It's the flat, patient stare of a dog who looks like she's been through this before. Dooby, meanwhile, is having the time of his life, even carrying a yellow toy through before he's back on his loop.

"She definitely hates him," their person wrote on @milolunaseries, home to Milo, Luna and Dooby. Hate is a strong word, though, for a dog who never once gets up and walks away. As one commenter put it, "She is so sweet." Sitting through all those laps without a single complaint, she really is.
