CAINZOS, R.P. et al. Utilidad de las respuestas rápidas de estrés para evaluar la evolución del tratamiento en un canino con fobia social. Rev. vet. [online]. 2012, vol.23, n.1, pp.49-54. ISSN 1669-6840.

Fear is an aversive state emotion to a real or perceived threat external situation. This emotion induces autonomic responses that alter homeostasis. When this situation is prolonged in time, health is affected. Aim of this work was to establish a relationship among routine clinical parameters -such as hearth and breath rates, pupil reflect with salivary production, salivary cortisol and behaviour response- for the evaluation of treatment evolution with paroxetin (1 mg/kg every 12 hours) associated to a behavioural therapy in a boxer bitch with social phobia, during the first month after adoption. Both heart and breath rates were between the normal range for the species during all the experiment (76 to 98 bpm and 18 to 40 bpm respectively. Regarding pupil dilation, on the first day the patient had mydriasis, but since day 15 she had myosis. Saliva production was more abundant on the first day, compared to days 15 and 30 (p<0.05); salivary cortisol did not show significant differences, with the highest absolute value on day 15 (1.22 μg/ml). Variables of both maintenance and social behaviours were significatively different during the entire assay (p<0.001). On the other hand, there was no adverse effect associated to paroxetin and the patient recovered the appetite, presenting heat during the second month. Clinical parameters associated with the autonomic nervous system result of practical interest to evaluate the treatment evolution of a phobic patient
