Devido a importância de conscientização dessa síndrome objetivamos avaliar a os tipos de distúrbios cognitivos em cães adultos/maduros através de questionário observacional e de testes de reatividade. Primeiramente, realizamos uma revisão bibliográfica abordando fisiopatogenia, métodos de avaliação, testes laboratoriais e formas de tratamento. Em seguida, elaboramos um questionário sobre comportamento com 28 perguntas, disponibilizado em rede social e respondido por tutores de cães acima de sete anos de idade. As questões foram dividas nas categorias de desorientação, interação socioambiental, ciclo sono-vigília, casa sujidade e atividade. Cada uma foi avaliada com escores numéricos, e com a soma da pontuação determinou-se que: o cão com disfunção cognitiva canina (DCC) acima de 50 pontos, o cão Borderline (BL) entre 40 a 49 pontos e sem alterações comportamentais (SAC) até 39 pontos. Também se avaliou há interferência na relação tutor/cão em caso de alteração comportamental. Além, do questionário foi realizado o teste de reatividade (open field, curiosidade, interação com humano e do espelho) com dez cães que apresentavam queixa comportamental, os quais seus tutores responderam ao questionário. Para a análise dos dados utilizou-se os testes ANOVA, as médias foram testadas com Tukey e qui-quadrado. Com relação ao questionário verificou-se nos 112 questionários respondidos, que 25,8% (29) dos cães apresentavam DCC, 41,9% (47) eram BL e 32,1% (36) eram SAC. Nas avaliações das categorias foi constatado que o grupo DCC obteve sempre as maiores médias do somatório, diferindo (p ≤ 0,005) do SAC e BL nas categorias a atividade e ciclo sono–vigília. Todos os tutores relataram no questionário que as alterações comportamentais não interferem na rotina do tutor com o seu cão. Entre os dez cães que participaram do teste de reatividade, constatou-se que dois cães tinham DCC, três eram BL, cinco eram SAC através da análise do questionário. Os cães com DCC tiveram alterações em todos testes de reatividade, exceto no de curiosidade. No open field esses animais urinaram durante o teste diferindo dos demais (p ≤ 0,05). No exame de interação com humanos e no do espelho os cães com DCC não realizaram a interação (p≤0,005) nem com a pessoa ou com o objeto, enquanto os demais grupos apresentaram a interação. Com os estudos realizados conclui-se que cães com DCC tem déficit cognitivo nas atividades, ciclo sono vigília, e interação social. / With increasing life expectancy of dog’s diseases related senility, has been studied, such as cognitive dysfunction syndrome (SDCC). Due to the importance of awareness of this syndrome, we aimed to evaluate the types of cognitive disorders in adult / mature dogs through observational questionnaire and reactivity tests. First, we conducted a literature review addressing pathophysiology, evaluation methods, laboratory tests and forms of treatment. Then, we developed a behavior on questionnaire with 28 questions, available on social network and answered by up dog guardians seven years old. The questions were divided in disorientation categories, socio-environmental interaction, sleep-wake cycle, house soiling and activity. Each was evaluated with numerical scores, and the sum of scores was determined that: the dog with canine cognitive dysfunction (DCC) above 50, the dog Borderline (BL) from 40 to 49 points and without behavioral changes (SAC) to 39 points. Also evaluated for interference in the mentor / dog relationship in case of behavioral change. In addition, the survey was conducted the reactivity test (open field, curiosity, with human interaction and mirror) with ten dogs with behavioral complaint, which his tutors answered the questionnaire. For data analysis, we used the ANOVA tests, the averages were tested with Tukey and chi-square. Regarding the questionnaire there was the 112 responses, 25.8% (29) of the dogs had DCC, 41.9% (47) were BL and 32.1% (36) were SAC. In the evaluations of the categories it was found that the DCC group always had the highest average of the sum, differing (p ≤ 0.005) of the SAC and BL in the categories activity and sleep-wake cycle. All tutors reported in the questionnaire that behavioral changes do not interfere with the tutor of the routine with your dog. Among the ten dogs that participated in the reactivity test, it was found that two dogs had DCC, three were BL, and five were SAC by questionnaire analysis. Dogs with CHD had changes in all reactivity tests, except curiosity. In the open field the animals urinated during the test differed significantly (p ≤ 0.05). In the examination of interaction with humans and the mirror dogs with CHD did not perform the interaction (p≤0,005) or with the person or the object, while the other groups presented the interaction. With the studies, it was concluded that dogs with CHD have cognitive impairment in activities, sleep wake cycle, and social interaction.
