I want to have my China Doll spayed, but I have read several conflicting reports on what age it should be done. She is going in on Friday for her second set of shots (she is 10 weeks old tomorrow), and the staff at the vet says they can spay her then if I want. Should I be concerned about having her anesthetized at such a young age? I certainly want to have it done before she is 6 months old. She is already showing some signs of wanting to "mark her territory" and finds places where my mother-in-law's dogs have "went" to go, even if she doesn't have to go. Will having her spayed earlier help to correct this? I have heard that early tendencies of marking territory can lead to aggression toward other dogs as she grows older. I know that proper socialization can help to prevent aggression so we are working on that too. Any help with when would be the ideal time to have her spayed would be much appreciated. Thanks!
