“…Ageing in dogs is associated with the decline of several cognitive domains, such as learning, memory, visuospatial function, executive function, and attention (Folstein et al 1975;Head 2014;Landsberg et al 2012;Mongillo et al 2013;Svicero & Amorim 2017;Wallis et al 2014). The visuo-spatial memory domain is particularly interesting, because its decline precedes the onset of declines in other domains.…”

Decline in the visuo-spatial memory domain may be an early marker for cognitive decline and has a relevant impact on animal welfare. Current research on visuo-spatial memory in family dogs is often limited byfactors such as the need of extensive pre-training, limited attention to co-occurring medical conditions, a focus on laboratory dogs, or low sample size. Therefore, we aimed to develop a test that relies on visuospatialshort-term memory, may be performed in a short time, and does not require explicit training. We tested a large sample of young and old dogs, finding that young dogs were more likely to perform correctly, although performance decreased with consecutive trials in both age groups. However, groups did not vary in the severity of mistakes. This task represents the first measure of dogs’ age-related decline of short-term spatial memory that does not require explicit training. The test could potentially be used in veterinary behaviour contexts to monitor cognitive changes in ageing dogs, utilizing a simple binary measure ofsuccess.

“…CCDS signs were more frequent in dogs with ≥ 10 years of age (31.4%) when compared to dogs with ≤ 9 years (17.90%) (p < 0.006). In the present study, it was observed that an increase in canine age increased the probability of developing changes in cognition (NEILSON et al, 2001;AZKONA et al, 2009;KATINA et al, 2016;SVICERO et al, 2017). As the number of mature and elderly adult dogs increases (AKZONA et al, 2009), it is becoming essential to perform a cognitive evaluation of these dogs, as part of a clinical routine, since longevity cannot be considered proportional to quality of life (KATINA et al, 2016).…”

“…It is important to note that aging leads to a decline in cognitive status and predisposes behavioral changes (LANDSBERG et al, 2008;ARAUJO, 2005). This was also demonstrated in clinical studies conducted in Brazil, Spain, and Turkey, where the dogs studied had more evident and serious signs of CCDS as the age increased (BENNETT, 2012;GALLEGO et al, 2010;SVICERO et al, 2017).…”

“…Regarding other parameters of the animal review, no statistical differences were demonstrated between dogs with and without compatible CCDS signs ( Table 1). The research carried out tends to show that there is no predilection for breed, sex, reproductive status, and size (ROFINA et al, 2006;FAST et al, 2013;SVICERO et al, 2017). As well as a higher risk factor for male dogs to develop CCDS (SVICERO et al, 2017).…”

“…This reality has resulted in the need to diagnose and intervene earlier in diseases related to senility because with the increase of age, the disorders related to cognition become more frequent (PÉREZ-GUISADO, 2007). With the increase of a dog's age, neurobehavioral alterations related to consciousness, perception, memory, and learning begin to occur resulting in a decline in the cognitive and behavioral capacity, known as canine cognitive dysfunction syndrome (CCDS) (SIWAK, 2002;ARAUJO, 2005;OSELLA et al, 2007;GONZÁLEZ-MARTÍNEZ et al, 2012). These cognitive changes can be obtained from owners using observational questionnaires and classified into categories named through the acronym DISHA (Desorientation, Interactions, Sleep, Housetraining, Activity) (NEILSON et al, 2001;LANDSBERG et al, 2008;OSELLA et al, 2007).…”

The life expectancy of dogs has increased in recent years, mainly due to intensified care by owners, through health care, nutrition, and wellness. Currently, we have a large population of elderly dogs and consequently, the development of age-related conditions, such as cognitive dysfunction syndrome (CDS). Thus, we aimed to identify signs compatible with canine CDS (CDS) in dogs, through investigation of daily behavioral changes. We collected data from review, interaction with other animals, and the behavior of dogs. An observational questionnaire was used to evaluate behavioral changes. The responses generated a summation of points for the classification of dogs with and without signs compatible with CCDS. We also evaluated the interference of behavioral changes in the cohabitation of the owner with his dog. Of the 178 dogs studied, 40 (22.4%) had signs compatible with CCDS, especially those aged ? 10 years (31.4%). There were no statistical correlations with variables of sex, reproductive status, size, and race. Statistical differences were observed regarding the frequency of behavioral changes between dogs with and without CCDS in relation to disorientation, activity, sleep/wake cycle, house/soil, and socioenvironmental interaction. The owners considered that dogs with CCDS alter their daily routine and were favorable to initiating treatment, although with reduced compliance for life-long medication. We conclude that dogs older than 10 years have signs compatible with CCDS regardless of race, sex, reproductive status, and size. They present changes mainly in behavior related to activity, socioenvironmental interaction, sleep/wake cycle, and house soil and, less frequently, the manifestation of disorientation.

O alto nível de relação entre humanos e animais de companhia intensificou a preocupação de alguns tutores com as desordens relacionadas ao envelhecimento. Durante a velhice, além de mudanças fisiológicas, alterações patológicas como a Síndrome da Disfunção Cognitiva Canina (SDCC) são comuns. Essa doença é caracterizada por processos degenerativos que culminam em perda gradual da função cognitiva, sendo frequentemente confundida com o processo natural de envelhecimento. Neste contexto, objetivou-se avaliar a ação de um suplemento nutricional à base de aminoácidos, prebióticos e ácidos graxos para cães idosos na evolução clínica da SDCC. Foram avaliados 67 cães em idade sênior (> 7 anos) para positividade aos sinais clínicos da SDCC. Posteriormente, os animais positivos (n=15 / 22%) foram alocados em dois grupos experimentais, controle (C) e tratamento (T- utilização do suplemento nutricional). Observou-se melhora, relatada pelos tutores, de sinais clínicos associados à SDCC em 80% dos animais tratados, no entanto mais estudos são necessários para elucidar o efeito de suplementos nutricionais na regressão da sintomatologia clínica de cães com sinais clínicos sugestivos da doença.
