“…Among others, it was shown that dogs are capable of social learning (e.g. Pongrácz et al 2001), including various instances of imitation where in some specific cases we have convincing evidence for imitating novel actions through episodic memory as well (Fugazza et al 2016). Dogs not only have a given identity, but they are also able to recognize their own names, even amidst distracting verbal background noise (Mallikarjun et al 2019).…”

“…Thus, it is reasonable to assume that dogs may possess a complex enough mental representational system and also an ecologically valid need for at least some form of representing the self. In the case of dogs, there were sporadic efforts where some components of self-representation were tested, such as the presence of episodic-like memory (Fugazza et al 2016). It was another approach, when they investigated the ability of the discrimination of own odor from others' (Bekoff 2001;Gatti 2016;Horowitz 2017).…”

That dog won’t fit: body size awareness in dogs

With very few exceptions, no coherent model of representing the self exists for nonhuman species. According to our hypothesis, understanding of the Self as an object' can also be found in a wide range of animals including the dog, a fast-moving terrestrial predator/scavenger, with highly developed senses and complex cognitive capacity. We tested companion dogs in three experiments in which they faced three different variations of the same physical challenge: passing through an opening in a wall. We predicted that if dogs are capable of representing their own body size, they will react differently when faced with adequate or too small openings. We found that dogs started to move towards and approached the too small openings with significantly longer latencies than the suitable ones; and upon reaching it, they did not try to get through the too small openings. In another experiment, the medium-size (still large enough) opening was approached with latencies that fell between the latencies measured in the cases of the very large or the too small openings. Having discussed the potential underlying mechanisms, we concluded that our results convincingly assume that dogs can represent their own body size in novel contexts.

“…Il s'agit donc d'une mémoire à long terme du « quoi ». Ils sont ainsi capables d'imiter une action, réalisée par un homme (par exemple, toucher une cible avec le nez), et de la reproduire sur commande, quelques minutes, voire une heure, après la démonstration [23][24][25]. Au-delà du critère de durée, la mémoire à long terme est subdivisée en deux sous-types de mémoire : la mémoire explicite (ou déclarative), qui correspond au souvenir conscient.…”

“…Le premier est l'absence d'encodage actif de l'information durant la phase d'exposition à l'événement : le sujet ne cherche pas, de façon active, à se rappeler ce qui vient de se passer. La nature accidentelle, accessoire, de la mémorisation est une propriété essentielle pour parler de mémoire épisodique [24,42]. Le second critère est que le sujet se rappelle de l'événement en l'intégrant dans son autobiographie « qui, quoi et quand ?…”

The ability to remember past events in all of their dimensions (what? where? when? i.e. autobiographic/episodic memory) is highly adaptive. Conversely, individuals who do not have such ability are less likely to benefit from recognizing situations similar to previous ones, e.g. to avoid being defeated several times. We will present the different types of memory and their ontogeny, focusing on those that are found in dogs. We will then describe more precisely the episodic memory, i.e. remembering events or actions from others, and their location and the time of the events and will present to which degree such a skill is found in dogs. We will show that, even if dogs are a social species whose specificities should reveal the existence of an episodic-like memory, dogs remember who and what happened but no study evidenced yet that they remember the precise time it was done. Further studies are thus needed, especially as dogs represent a relevant biological model for comparative cognition to study the ontogeny or senescence of non verbal episodic memory.

“…This new field has given rise to studies that show dogs may be comparable with humans in tasks involving learning and memory, especially complex memory types such as episodic memory (Fugazza, Pogány, & Miklósi, 2016). It is even suggested that dogs may be an ideal animal model for the study of human agerelated diseases affecting memory, such as Alzheimer's and dementia (Cummings, Head, Ruehl, Milgram, & Cotman, 1996).…”

Incidental spatial memory in the domestic dog (Canis familiaris)

We built upon previous work by Fujita et al. (2012, Animal Cognition, 15(6), 1055-1063) to create an experiment that investigated the presence of incidental memory for the spatial location of uneaten food in the domestic dog. Here, we dissociated potentially incidental spatial memory from the incidental memory for the characteristics of objects, in this case, food bowls. Eighteen household domestic dogs of various breeds and age were presented with four bowls. Each bowl contained either a novel object, treats the dog could consume, treats it could not consume, or it was left empty. Following a delay, the dogs returned to the laboratory and were presented with empty bowls in the same spatial orientation as the initial exposure and could move freely between bowls. This experiment required no previous training outside of basic obedience and so avoids the possibility that performance on the test was a conditioned response. We hypothesized that domestic dogs would be able to remember the location of uneaten food when presented with an unexpected memory test. We found that dogs in this study showed no evidence that they encoded spatial location in the absence of other cues that could be used to distinguish food bowls at specific locations. This suggests that dogs in previous experiments were more dependent on incidentally encoding the "what" and "in what" of this task than the "where," in the absence of features making each location distinct.
