As a new pet parent, it's difficult to imagine life before your amazing furry friend. But do you ever wonder if your pup feels the same way about life with you? Do dogs remember their owners from past homes? Do dogs have memories, even?
There's still research to be done on just how much dogs remember, but here's a look at what's known today.
Do Dogs Have Memories?
It's proven that dogs have memories, but researchers don't quite know the specifics yet, including to what extent dogs remember things.
"There are many stories about the memory of dogs, but only a few experiments have been done," said Ádám Miklósi, head of the ethology department at Eötvös Loránd University in Hungary, in an article for Dog Fancy.
The good news is that studies about dogs' memories are underway, including at the Duke Canine Cognition Center at Duke University, where researchers are looking at the following questions: "What cognitive strategies do dogs use when navigating or remembering events? Do all dogs navigate and remember things in a similar way? Are there systematic breed differences?" Any of these questions could lead to compelling discoveries.
Dog Memory Types
With a lack of empirical evidence regarding how a dog's brain "remembers" things, when faced with a question like "Do dogs remember their owners?" a good follow-up question is, "How do we even know?" Luckily, dogs are great test subjects (Sit? Sure! Fetch? You bet!), which allows experts to extrapolate information based on a dog's behavioral patterns.

We know that dogs can be smart, but not enough research has been done to determine whether or not memory capacity differs from one dog breed to another. Generally speaking, dogs exhibit varied types of memory cognition, including the following.
Memory Span
Dogs have a very short short-term memory. "Dogs forget an event within two minutes," reported National Geographic, citing a 2014 study performed on various animals from rats to bees. Other animals have long-term memories, such as dolphins, but dogs don't seem to have a long-term memory that lasts much beyond those two minutes.
