I will eventually have another Chi. I would like a boy. People have tried to scare me off males because they say they spray all over the house. I have had two other males (terrier and golden retriever) they never did. I was told if they are spayed early enough they will not "mark" their territory. But do any of you have experience owning both male and female Chi's. Do any of you who have males see this as a problem? Any difference in temperaments between your male and female?
