lease ’s say your long - full term human relationship totally implode . Browsing for a newfangled flat , or a healer that takes your indemnity , you hear your dog bark in the other room — and agnise , with a start , that it ’s not actually your dog . Once you ’re all moved out , the dog will be out of your life , too . stew in self - pity you think — and later on become convinced — that this dog , who you ’ve fed and bathed who knows how many times , and coined several endearing nicknames for , will forget you ever existed by the start of next leaping .
Probably , for your own health , you should just invalidate those kinds of thought . Still , the question remains : Are you correct ? Can a dog draw a blank one of the masses in its life-time , if that person of a sudden leaves it for a foresighted ( or long - ish ) period of clip ? To find out , for this week’sGiz Askswe progress to out to a act of experts in canine behaviour , psychological science and medicament . As it turn out , this aspect of dog - memory is unmanageable to learn : systematic inquiry on the subject area is close to non - existing . But a vast body of anecdotic grounds evoke that , barring a neurodegenerative illness , your Canis familiaris will probably never fail to recognize you .

Most pet owner will fit in that their pets can commemorate things . One object lesson : a dog get excited to head out for a walk after catch or hearing a collar . Or a dog con to associate commands with actions — sitting when say to sit . These reflect semantic memory , a type of explicit memory board , where previously see data is recalled .
grounds for semantic memory in animal has been find across a variety of mintage . In dog cognition study , many experimental paradigms utilize a dog ’s semantic memory to assess other aspects of their cognitive abilities . However , the question of “ can dogs forget their owners ? ” employ another case of explicit computer memory call episodic memory .
Illustration: Chelsea Beck (Gizmodo)
Episodic memory refers to memories of autobiographic event — in other words , recalling personal experience . Endel Tulving , who defined episodic and semantic memory , proposed that witting recollection was required to demonstrate episodic memory . Given that we have no good style of evaluating consciousness , also know as self - awareness , in animals , it is incredibly thought-provoking to suggest that frankfurter , or other animals , have episodic memory board .
To get around this definitional restraint , researchers have separated the behavioural criteria require for occasional computer memory from the conscious component and term this “ episodic - like ” memory . Using this definition , animal behavior researchers can now evaluate whether or not animate being behaviorally demo the recalling of autobiographical events .
To date , there is evidence that some non - human animals , such as with child aper , dolphins and chaparral John Jay may own some form of episodic - corresponding memory . But how about our dog ? Are they up to of occasional - same retentiveness ? Can they remember us — or forget us ? In a 2016 field of study , Claudia Fugazza and colleagues evaluated occasional - alike retention in dog . The results propose that dogs can recall their owner ’s actions , even in illustration in which they were not explicitly overtop to do so . These finding bespeak that dogs may have episodic - comparable store in which store are linked to specific metre and position .
While we may not yet screw the answer to “ can dogs forget their owner ? ” , it seems plausible that the grounds for episodic - similar memory board , in the form of retention related to clock time and space , may carry to remember things like “ who ” . We need more research to uncover the solvent to this question , but for now , it ’s nice to come home to a dog , that in our mind , appears happy to see us .

Many animate being have excellent retentive - full term store . A foresightful - terminus memory , as the name hint , can persist integral without significant abasement for years . Anecdotes about favourite recognize their first owner , or another substantial somebody in their life , after many years are supported by experiments on animal retentiveness , in which beast have been trained to distinguish epitome and then had their memory try months or even twelvemonth later . In fact , even pigeon , who are not considered too sound by laic people , can commend hundreds of images for many calendar month .
The question is more whether the memory is formed in the first place than whether it will be remembered , once formed . For the most part , animate being form farsighted - term memories of events and situations that they deem meaningful . If a person is particularly miserly to the brute , they might form right aside a very strong aversive retentivity , and thereafter react with fear or aggressiveness . If a person forges a long term alliance through day-after-day , positive interaction , that somebody will likewise be remember for many year . I am not positive that casual acquaintance will be remembered as well .
Memories of other beings ( animate being or man ) are more well form in societal animal , such as dogs , horses , or parrots . Cats are more solitary and therefore they do not palpate powerfully about the simple presence of other beings . At the same time , it ’s hard to imagine that extensive positive fundamental interaction will not form a memory at all . Moreover , because they are less social , cat are also less expressive of their emotion , so they might still remember someone but not be very vocal about it . I ’m afraid this will be another point of contestation between dog people and cat people .

Forgetting , memory , love , and attachment . These words line the human experience of see delight in another . Sometimes when we are away from the other person , we think about them , and then we experience joy at seeing them once again . For people , these unconscious process involve linguistic process , which enables us to cover abstractionist concept and talk about events that happened in the past . For dogs , there is no grounds that they have this intragroup monologue . Fortunately , read can also involve non - language associations between events , such as when we associate a smell with a pleasant natural event , or when we begin expend more time with someone because they make us experience respectable . These connection can find without our being able to identify what is pass , and they can last our entire life with only a few initial experiences . These associative processes ( responder and operant conditioning ) are how firedog learn .
Sometimes these associations do not serve us well in our day-by-day life ; we seek to block painful or irrelevant association . One means to draw a blank is to undergo counterconditioning , or systematic desensitisation . connection can also break over the passage of time , if we go without exposure to relevant clue .
For all of us , the perdurable nature of association with others is a double - butt against sword . For example , a Canis familiaris might respond to a previous caregiver they have n’t get a line in eld with exuberant butt - wiggling , and a frank ’s reverence of man in baseball game detonating equipment might also suffer for years . creature tax shelter staff and volunteers are familiar with the counterconditioning process in which they overcome a domestic dog ’s negative experience with mass in the past tense by creating a new connexion : masses equal delicacy / toy / adept times . For a dog with a lot of minus past experience , this outgrowth is obtuse and deliberate , and the trainer minimizes jeopardize stimuli by introducing new things cautiously . Dogs , like people , determine best when they ’re calm . In fourth dimension , and with the trainer ’s skill , the past is less influential on the domestic dog ’s behavior , and the dog learns that citizenry are fun . For dogs with plus past experiences , these associations with their previous owner also fleet over time as new sources of treats and cuddle arise .
So , yes , dogs can forget . While the melodic theme that our pet could forget about us may be disappointing , this ability to forget is actually something that we admire most about dogs : they do n’t hold score , and they are remarkably adaptable to their current circumstance . Without the internal language processes of chew over , rumination , fixation , and analytic thinking , they live on in a simpler world of pardon and new beginnings .

There are no controlled study of this that do to beware . However , the greeting behavior of dogs is ordered , and a feature catch by owners as a feature of a unadulterated dog — and dog owners rate their dog as splendid on this trait . It ’s an example of built - in compatibility and shows that dog realize their people . However , as wienerwurst age some have cognitive deficits and no longer agnize their owners , which can be very worrisome . farseeing term health care provider of elephants sometimes have not seen the elephant for even tenner and then been fully spot by the elephant .

College students go home for winter breach will undoubtedly be greeted rhapsodically by the canine tooth sibling they lead behind and feel re - guarantee that they were not forgotten . Such were the experiences described by the Nobel prizewinning ethologist Konrad Lorenz in his insightful account book Man Meets Dog . For example , returning home after nine calendar month , Lorenz report how Stasi first catches his perfume , then howls deliriously for more than a minute before bounding and leap towards him in frenzied excitement . The vividness of her welcome is hard to explain in any way other than that she recognise her possessor .
But might a hotdog forget her absentee clique appendage after a longer separation ? It seems improbable for a number of reasons . Odor memory appear to be super robust and long - lasting . The French writer Marcel Proust famously describes the remindful power of the scent of a Madeleine cooky soaked in teatime to enrapture him back in time to his aunt ’s kitchen . With a nose and brain built to process olfactory input , a dog is not likely to blank out what scents mean , peculiarly when they belong to members of their family and have unassailable aroused connections . to boot , contextual cues are known to aid memory recovery , which would help the dog ’s power to recognise the odor walking through the front door . But there may be an exception . Like human race , dog are living longer ; and , like human race , they can develop symptom of dementia . A dog with canine cognitive dysfunction might forget his owner but how would we really get laid ? The lack of a response can be very difficult to interpret .

Canine Alzheimer ’s is decidedly a real stipulation . I do call it Canine Alzheimer’s — the purist will say , “ well , it ’s not exactly the same , ” but it kind of is exactly the same , right down to the changes that occur in the brain . In humans with Alzheimer ’s , there ’s a build - up in the brain of a protein called amyloid . ( There ’s another protein involve , but amyloid is the independent perpetrator . ) The degree to which the brain is regard correlate precisely with the point of psychomotor impairment in the someone , and the same is dead on target in dogs . One of the cardinal signs of Alzheimer ’s is freak out , and freak out require not recognizing familiar the great unwashed . So disease can have it , and I imagine there are other neurological conditions that could as well .
But you look at all the telecasting on YouTube of soldiers who ’ve been away in various dramatic art of war for long period of sentence — they return and the pet goes absolutely ballistic . Or think of the renowned story of Greyfriars Bobby in Edinburgh , Scotland — this was a andiron whose possessor died and was interred in a church graveyard , and ostensibly the dog spent the next nine or ten years just sit on the grave , waiting for his captain to come back . And there was a Japanese hound who always met his possessor off the train at a certain time , and who still went down to match the train for yr after the owner expire of a affection onset , hoping he would get off .
These storey sort of corroborate that dogs have incredibly retentive memories for hoi polloi they ’re fond of . And with hoi polloi they ’re fond of , they remember everything about them — every nuance , from visual aspect to smell . All their sense are acutely tune up to that person .

Darwin , when he went around the man on the Beagle , was very impressed by the fact that when he got home four years later his dog clearly know him . And plenty of less famous people than Darwin have had the same experience .
But as for the reverse — fount where people were aside from their dog for some flow of time , and the dog-iron did not recognize them when they pass — I can not think of any instance where that happened . It ’s one of those thing that might have happened , but nobody would want to boast about it .
But just because dogs remember their people for years does n’t mean it ’s brutal to rehome a wienerwurst . I find very strongly that more people should be adopting old dogs , or frank from shelters , as opposed to thinking you have to have a puppy — thinking that you wo nt really have a loving animal if you did n’t have sex the dog when it was a pup . And that ’s just not true . domestic dog can form strong emotional bonds with hoi polloi even if they do n’t assemble those people until well by and by in their lives .
