I have a 10 month old Dachshund puppy who has just gone into heat. I have a 2-year old male Dachshund. I am trying to prevent her from getting pregnant this young. I was just informed by a friend that it is dangerous for a dog to get pregnant on their first heat-cycle. If she does get pregnant, I need someone to tell me what is dangerous, and what steps I could take to ensure that this pregnancy goes safe and smoothly. Please get back to me urgently
