I have a two year old GSD bitch. I am considering having her spayed. Not to reduce the chance of whoops litters. I have had unspayed bitches all my life. At those times, it is like simply controling your teenage daughters. But spay to prevent the chance of pyometra. The chance of pyometra has been studied in unspayed Golden Retrievers, in GSDs it is less. Inga has reached her full maturity. I am wondering, would it change her disposition and how would it change her physically?
