It is now a well-known fact that, like us humans, even our four-legged friends remember other dogs very well and manage to identify those of their own kind that they have already met, even months later.
A study published in the November 2016 edition of Animals found that canine grieving behaviors — and how long they last — can vary from dog to dog, according to Dr. Jennifer Coates, DVM, an advisor for Pup Life Today. “Typically, their behavior returned to normal within two to six months.”
History of Dogs' Memories
Those that remain with their mother for the first 8 weeks tend to remember her (as well as their siblings) in later life. Similarly, females who are with their puppies for 8 weeks and beyond imprint a memory of them, and will show signs of recollection, even once they reach adulthood.
Research strongly supports that dogs remember and recognize their human companions. A 2020 study published in Animal Cognition (Eatherington, CJ, et al) found that dogs can recognize their owners through photographs, with a higher probability that male dogs would recognize their owners.
Memory Span
"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.
It is very likely your dog can remember things that have happened in the past and especially events that happened recently, like where they left their ball outside yesterday. So in short, your dog can probably remember certain things from the day before!

The American Kennel Club says changing owners can be traumatic for dogs. Losing their owners can make dogs stop eating, lose weight, lose interest in physical activity, and exhibit symptoms of canine depression. That's why you must take any decision to re-home dogs seriously.
While they might not understand the full extent of human absence, dogs do understand the emotional feeling of missing someone who's no longer a part of their daily lives.
After a 2 year project, Psychology Today reported that “Yes, dogs miss us when we're gone!” In another study it was found that after 2 hours absence, dogs greeted their owners more vigorously than after only 30 minutes of being left alone.
Although dogs can't identify themselves in the mirror, they still have some level of self-awareness and ace other self-recognition tests. They can recognize their own odor, and recall memories of specific events, Earth.com reports.
When a dog loses a companion, two- or four-legged, he grieves and reacts to the changes in his life. Dogs alter their behavior when they mourn, much like people do: They may become depressed and listless. They may have a decreased appetite and decline to play.
Indeed, like much of what we imagine goes on in our dog's minds, the idea that they can recognize their own breed is mostly fiction. Mostly. Dogs can recognize other dogs, as opposed to cats and bears and other species.
Provide closure.
Pets have a limited understanding of death as finality. It's tough, but if possible, let your pet see the body of his deceased friend. He may not totally grasp the situation, but one last visit may help him understand that his pal is gone.
Dr. Brian Hare, who has written books about canine cognition, told People that dogs have emotions and feelings just like we do. Here's what he said about love: "Yes, your dog knows how much you love him!
Hunting and tracking dogs can identify animals from far away even without seeing them, just based on their smell. As you may know, this skill comes in handy for humans, as a dog's sense of smell is often used for the following purposes: Track Animals. Track or find humans.
Overall, dogs are complex creatures that think about a wide range of things, including social relationships, their physical environment, daily routine, physical needs, and health and well-being.
When you kiss your dog, you may notice signs that indicate they know that the kiss is a gesture of affection. As puppies, this is not something that dogs would recognize, although they would feel you doing it. However, as they get older they associate the kisses and cuddles with you being happy with them.
So, yes, a puppy can definitely think of you as his “mother” — that is, his provider and protector — and develop as strong an emotional bond with you as if you were blood-related. Your puppy will also quickly learn to pick you out among strangers, both by sight and through his powerful sense of smell.
Patricia McConnell, PHD, Certified Animal Behaviorist and author of several books related to dog behavior, believes that dogs remember their previous owners, however they don't remember in the same capacity as people do.
The grief of rehoming tends to be layered with emotions such as guilt and shame. You may feel like you'll never forgive yourself for this decision. Giving a pet up for rehoming is never easy and there are very few people who can do this without any misgivings.
Symptoms of PTSD in dogs can include: panic, panting, fearfulness, being timid and clinging to their owners, aggressive reactions in dogs that were never aggressive before, depression, and hyper-vigilance (especially for working dogs and guard breeds).
Dogs can actually start missing their owners from the moment they part ways, and keep missing them more up until two hours. Beyond two hours, the melancholy stays about the same until they're reunited with us.
Dogs have a great sense of smell and can often recognize other dogs by their scent. However, they also rely on visual cues to identify different dog breeds. For example, a small dog may look up at a large dog and think, that's a big one! Conversely, a large dog may see a small dog and think, that's a little one!
Research suggests that dogs with a guilty look do not show evidence that they are aware of having engaged in misbehavior. One would not experience guilt if one were unaware that a crime had been committed.
