A video of an excited dog called Ivy has recently racked up 1.4 million views on TikTok.

The footage posted by Katie Duran (@katieduran9), shows her pulling up at a Starbucks drive-thru with Ivy next to her in the car. But before Duran can put on the brakes, Ivy rushes over to stick her head out of the driver's side window, eagerly waiting to say hello to the kiosk worker.

Ivy isn't fully grown yet, but female goldens can grow up to 22 inches and weigh 55 to 65 pounds. The clip's caption says: "She still thinks she [is] that same 10lb puppy."

During the video, Duran tries to move Ivy to the back seat by grabbing her collar, but the excited dog doesn't stay there for long. The reason for Ivy's enthusiasm becomes clear by the end of the clip. She receives a special treat from the coffeehouse staff—a pup cup from which she eagerly slurps directly out of the worker's hand.

Do Dogs Know Their Size?

Like this dog owner, you may be wondering if dogs are aware of their size. In 2019, a group of researchers in Hungary at Eötvös Loránd University's Department of Ethology had the same question.

They investigated the components of canine self-representation by testing dogs' ability to gauge whether they could fit through varying sizes of doorways without previous exposure to the setup.

The experiment aimed to see if dogs could assess the size of the openings and decide whether they could pass through them based on their body size.

The findings indicated that dogs are capable of such size awareness. They adjusted their behavior based on the size of the openings, showing hesitation or refraining from attempting to pass through when the door was too small for them.

This suggests that dogs have a modular form of self-representation, where body awareness is a significant component, distinct from the visual self-recognition often assessed in other animals using mirror tests.
