Chemical sterilization of dogs using single bilateral intra-testicular injection of calcium chloride or clove oil

The current study was designed to evaluate the efficacy of single bilateral intra-testicular injection of calcium chloride or clove oil to induce chemical sterilization in ten dogs divided into two groups each of five animals. Chemical sterilization was evaluated by clinical signs, hormonal analysis and histopathological examination. Testosterone level was decreased significantly after injection of both agents with complete degeneration of the interstitial leydig cells and seminiferous tubules while cortisol level was increased during the 1[st] week after calcium chloride injection. The single bilateral intra-testicular injection of calcium chloride or clove oil proved to be accepted as a suitable alternative to the surgical sterilization of dogs; however clove oil was superior to calcium chloride as it induced less pain and irritation to the dogs

Evaluation of pinhole castration technique compared with traditional method for castration in dogs

Castration is the most common routine surgical procedure in animals.The present investigation aimed to compare between two techniques of surgical castration [prescrotal and pinhole] in dogs. The study was performed on nine clinically healthy dogs weighing 20-30 kg and aged from 1-2 years, these animals were divided into three groups [prescrotal, bilateral pinhole and unilateral pinhole] and each group consists of three animals. Castration was done under the effect of xylazine -ketamine anaesthesia. Intra-operative and post-operative complications together with cortisol concentration and histopathological examination were reported. The result of this study revealed that no major intra and post-operative complications were observed in prescrotal technique. Healing score is better in prescrotal than pinhole technique while cortisol level was significantly higher in pinhole technique. It was concluded that prescrotal castration technique proved advantageous than pinhole one as it was less painful, simple and effective for male dog sterilization
