Neutering a male dog can sometimes be a difficult decision for many pet owners. Without a doubt, neutering male dogs causes a drastic drop in testosterone levels, and some pet owners feel that the quality of their dog’s life is affected as a result.
Spaying is the term commonly used for an "ovariohysterectomy", the surgical removal of the entire reproductive system including the uterus and ovaries of a female dog or cat.
This is a question that veterinarians are asked frequently. Many pet owners think that it is beneficial to allow their pet to have a litter before spaying or neutering is scheduled. A litter is a set of babies or offspring born together.
