In Sweden, the most common way to castrate a bitch is by midline approach. In this study, flank and midline approaches are compared in order to evaluate incision by the flank as an alternative technique for ovariohysterectomy in the bitch. The study was performed on straydogs in the central part of Thailand under field conditions. 32 bitches were included in the study. The castration technique was by flank and midline approach, alternating with every other bitch.

This student report is about neutering male and female cats and compares early ageneutering to neutering at the traditional age of 6 months.The main focus in this report is early age neutering, which means that neutering isperformed when the kittens are between 6 and 16 weeks of age. This technique has beenused by shelters in the United States for a long time, to prevent the adopted cats fromreproduce and contribute to the problem of overpopulation.Two different surgical methods are also addressed; the ventral midline incision and thelateral flank approach. Ovariohysterectomy and ovariectomy are also compared.I also address which drugs are preferable when kittens are neutered and some importantguidelines where you have to be extra careful when dealing with kittens.These guidelines are the preanesthetic evaluation, calculating drug dosages and preventinghypothermia, hypoglycaemia and stress.The report also has a summary of the concerns regarding early age neutering such asanaesthetic risks, growth disorders and growth plate fractures, urologic diseases andimmune system dysfunction, obesity, altered metabolism and behavioural changes.The sex hormones and how they change after neutering is also included.At the end of the report there is a compilation of a questionnaire that consists of eightquestions that I sent out to various animal hospitals and veterinary clinics in Sweden..
