1.有一本書<The Golden Retriever Handbook by D. Caroline Coile>在Dominance aggression部份,提到了與結紮的關聯性。作者(D. Caroline Coile)認為結紮不一定能減輕Dominance aggression,甚至對母狗來說會阻礙醫生的治療。不知您的看法是如何? (節錄:Dominance aggression is more common in males than females, and occasionally (but not always) castration can help. Spaying a female will not help, and may even hinder curing dominance aggression)
