Dogs Remember Their Lives With Past Owners

Dogs can spend hours sitting in a window waiting for their owners to return home from work.

While they don't understand why their owners leave them behind, they're always excited for their return in the evening.

As owners, we suspect our pets think we have abandoned them, with our daily departure seeming to come as a shock to them each and every time.

However, a study, from the Department of Ethology, Eötvös Loránd University, in Budapest, Hungary, suggests dogs have an episodic-like memory, which enables them to recall events from their past, just like humans, meaning they should be able to anticipate our return.

The study describes episodic memory as "a memory of personal events and episodes in one’s life and, in humans, it is thought to be linked to self-representation because it implies the ability to represent the self in the past."

The scientific report, created by Claudia Fugazza, Péter Pongrácz, Ákos Pogány, Rita Lenkei, and Ádám Miklósi, investigates whether dogs remember their spontaneous past actions relying on an episodic-like memory.

A statement reads: "Dogs were trained to repeat a small set of actions upon request. Then we tested them on their ability to repeat other actions produced by themselves, including actions performed spontaneously in everyday situations.

"Dogs repeated their own actions after delays ranging from a few seconds to one hour, with their performance showing a decay typical of episodic memory."

In their findings, they state dogs use an episodic-like memory to recall their own actions, suggesting they have a "far more complex representation of a key feature of the self than previously attributed to dogs".

"We can, thereby, exclude the possibility that the dogs’ performance relied on a prepared behavioural response, in contrast with previous studies in non-human species that did not rule out this possibility e.g. dolphins'."

Thanks to their episodic-like memory, dogs should be able to recall key events in their lives such as their previous owners or spending time in rescue centres.
