Have you ever wondered how long your four-legged friends can keep their precious memories?
From heartwarming encounters to tricks we’ll never forget years later, dogs seem to have an uncanny ability to remember things that surprise us. But how well do they remember and perform cognitive skills compared to us?
In this article we will take you on an exciting adventure into the world of canine cognition and uncover the secrets of your dog’s memory.
A memoir about man’s best friend

These loyal companions and beloved best friends have a special ability to reach deep into our memories. But what about their memories?
When we study cognitive abilities and memory in dogs, there is no clear and precise way to give the right answer because dogs (obviously) can’t talk and they can talk to us. But sometimes actions speak louder than words, and researchers used behavior to find the answer to this mystery.
Certainly, we know from a variety of anecdotal evidence that dogs have very good memories. Because it has been proven that many dogs can remember their previous owners and even traumatic events that happened years ago. But of course, like people, individual memories between dogs can vary widely.
Pawprints Of Time
“There are many stories about the memory of dogs, but only a few experiments have been done,” Ádám Miklósi, head of the ethology department at Eötvös Loránd University, in Hungary, told Dog Fancy.
However, each year, there are more and more studies being done.
In 2015, National Geographic reported that “dogs forget an event within two minutes” [1], citing a 2014 study done by Johan Lind and his team at Stockholm University, Sweden.
On the other hand, Dr. Claudia Fugazza has obtained results that “dogs are able to remember a human action for more than 12 hours.” [2] One thing is for sure – canine cognitive abilities are more complicated than everyone thought.
In the most recent study, done by Dr. Fugazza and her colleagues [3], dogs were tested based on their episodic-like memory using a modified “Do as I Do” technique.
Basically, dogs were trained and tested on repeating a small set of actions, including some actions that are performed spontaneously in everyday situations.
Dogs showed the ability to repeat actions after delays ranging from a few seconds to 1 hour. Although their accuracy faded a bit over time (typical for episodic-like memory), the researchers were able to conclude that dogs are able to remember a lot more than previously thought.
A Dog’s Long-Term Memory
“Dogs and cats have different types of memories, just like we do. They have spatial memory, remembering where things are located, short-term memory, and long-term memory,” said Dr. Brian Hare, from Duke University, in Durham, North Carolina. [4]
There are many examples of dogs having long-term memory, both in real life and in different studies.
In a 1999 study conducted by Dr. Gillis C., it was found that dogs have an exceptional long-term memory of up to 5-and-a-half years. Researched dogs were able to recognize their kin even after being separated for a long period of time. [5]
However, examples of long-term memory can easily be found in everyday life.
For example, I’m confident that you have seen videos of dogs recognizing and being very excited to see their parent coming back home after spending years serving in the military.
The same goes for fears and traumas from the past.
“I have seen many patients who are scared of tall men, hats, certain noises, etc., which they can relate to a negative memory or event that has happened in the distant past,” said Dr. Jenna Sansolo, associate veterinarian at Ardsley Veterinary Associates, in Ardsley, New York.
Conclusion
Although more research is clearly still needed, so far, it has been proven that a dog’s memory capabilities are more complex and enduring than previously thought.
Dogs have demonstrated and continue to demonstrate the capacity to recall events, commands, and people even after extended periods of time.
Whether it’s reliving cherished moments or learning from past experiences, a dog’s memory is an integral part of what makes them our faithful and cherished best friends.
