Urethral catheterization after pharmacological induction for semen collection in dog.

The α-adrenergic agents are known to influence erection and ejaculation, and ejaculatory reflex is a primarily α-adrenergically mediated event. This paper aims to describe the urethral catheterization technique after pharmacological induction for semen collection in domestic dogs. For dose determination, semen collection was performed using increasing doses of dexmedetomidine (5 μg/kg, n = 2; 10 μg/kg, n = 2 and 15 μg/kg, n = 2) associated to 3 mg/kg ketamine in six animals.
