“…The ethogram was developed by using ad-libitum and all-occurrence sampling as previously described (ALTMANN, 1974;BEERDA et al, 1999b). Briefly, which were recorded in terms of frequency of occurrence or in terms of the duration of occurrence (BEERDA et al, 1999b).…”

“…The maximum secretion of cortisol in animals occurs in the first hours of the day (BEERDA et al, 1999b). Abandoned dogs taken into shelters and confined show high plasma cortisol concentrations during the first three days of confinement in the new environment (HENNESSY et al, 1997;DOWLING-GUYER;MARDER;D'ARPINO, 2011).…”

Á DEUS, que no silêncio das madrugadas, permitiu-me conhecê-Lo, entendê-Lo e me ensinou a conversar com Ele. Volto para casa com minha fé descoberta e com uma experiência íntima muito forte estabelecendo esta aliança. Graças dou! À minha mãe Otilia Wisniewski Lesnau pelas vezes em que cruzou o Brasil para socorrer minha família na minha ausência e o apoio que sempre ofereceu. A todos vocês, muito obrigado! Epígrafe "Dizem que a oportunidade é uma deusa que tem cabelo na testa, portanto você tem de apanhá-la quando ela vem de frente porque depois que ela passa, a única coisa a fazer é se lamentar". The mechanism of stress is already known and can be divided in two stages: acute stress, which releases thermogenic factors and inflammatory -mediated interleukin 6 (IL6) and chronic stress, which suppresses the inflammatory response and is mediated by the presence of cortisol. When stray dogs are housed in shelters, they undergo a period of adaptation; however, until now there is not a ressocialization program at the governmental level aiming to improve their welfare along with their new owners. The ressocialization program beginning when dogs arrive to the shelter and the correlation of dogs´ behavior with physiological and endocrine parameters related to stress have not yet been described , which raises the hypothesis that it can decrease the traumatic impact of abandonment. Twenty seven healthy bitches were divided into 3 groups: with owners, abandoned not trained and abandoned trained.The trained and abandoned dogs were later adopted. The training lasted 15 min / day for 21 days. The behavioral assessment (ethogram and ethotest) was performed every 7 days and physiological parameters assessment (heart rate, respiratory rate, blood oxygenation rate, pulse) as well as saliva collection, daily. After the adoption, the bitches were evaluated for 7 additional days. Data were analyzed by ANOVA, after testing the results for normality. The correlation between parameters was analyzed using the Pearson correlation test. Values were considered different at p < 0.05. The most surprisingly result was the maintenance of low levels of IL6 in trained dogs after neutering, whereas the other two groups showed a significant increase of IL6. The consequences of training were evident in ethograms after adoption: there was an improvement of the interaction of dogs with the new family, attitudes of playing were more numerous, and dogs showed a greater receptivity to the new owners. The tail wagging, as communication behavior, appeared much more frequently in trained dogs after adoption. Abandoned dogs after adoption manifested more idleness, discouragement and depression behaviors and reduced alertness.These results suggest that the training reassures bitches in the stressful shelter environment, improves their physiological parameters, controls fear behaviors making them more able to adapt to the new environment after adoption. There were no differences in cortisol among the groups (p > 0.05). However, IL-6 concentration was lower in ...

“…Desta forma, apesar de existirem diversos estudos referentes aos efeitos do estresse crônico sobre a função das adrenais em cães vivos (GARNIER et al, 1990;BEERDA et al, 1997BEERDA et al, , 1999, estudos com foco nas alterações morfométricas ou histopatológicas das adrenais em cães submetidos à necropsia estão ausentes.…”

“…A adrenalina (ADR) e a noradrenalina (NOR) são catecolaminas envolvidas na resposta ao estresse, sendo sintetizadas pela medula adrenal e, no caso da NOR, também pelos nervos simpáticos (ALOUSI; WEINER, 1966;WEINER, 1970;BLASCHKO;SAYERS, 1975 Os níveis plasmáticos de ADR e NOR refletem a secreção pela medula adrenal e, embora existam diversos trabalhos relacionados à quantificação plasmática de ADR e NOR em relação à causa de morte ou a demais situações de estresse em humanos ou em modelos animais (TOSO et al, 1993;HUTTUNEN, 1996;BEERDA et al, 1999;LUCOT et al, 2005;WILKE et al, 2007;ZHU et al, 2007), a obtenção de quantidades significativas de soro no sangue após a morte é dificultada pela coagulação disseminada. Na rotina de necropsia de pequenos animais, a possibilidade de coleta de sangue no pós-morte imediato é rara.…”
