By using large a sample of dogs than any used previously to examine behavior
in dogs, we found significant correlations between neutering dogs and
increases in
aggression, fear and anxiety, and excitability, regardless of the age at
which the dog was neutered. There were also significant correlations between
neutering and decreases in trainability and responsiveness to cues.

Behavioral and Physical Effects of Spaying and Neutering Domestic Dogs (
Canis familiaris)
Summary of findings detailed in a Masters thesis submitted to and accepted
by Hunter College by Parvene Farhoody in May, 2010.

Spaying and neutering domestic dogs is generally accepted as a relatively
benign procedure conducted on millions of dogs each year. The view of
spaying and neutering as benign and perhaps even beneficial to dogs has been
based on extremely limited scientific study of how gonadectomy affects dog
behavior and physiology. To investigate this, a 101-question survey called
the Canine Behavior and Research Questionnaire was used to collect
information on seven behavioral characteristics for 10,839 dogs. The C-BARQ
is a qualitative behavioral assessment instrument created by James Serpell
and his colleagues at the Center for the Interaction of Animals and Society
at the University of Pennsylvania. At this time, it is the only behavioral
assessment questionnaire that has been peer-reviewed and found to be
reliable and valid (Hsu & Serpell, 2003).
Behavioral characteristics of intact male and female dogs were compared with
those of four groups of neutered dogs: those neutered at or before 6 months
, between 7 and 12 months, between 13 and 18 months, and after 18 months.
Our data showed that the behavior of neutered dogs was significantly
different from that of intact dogs in ways that contradict the prevailing
view. Among the findings, neutered dogs were more aggressive, fearful,
excitable, and less trainable than intact dogs.
In addition, we measured eight individual bone lengths plus the height of
202 agility competition dogs to determine whether gonadectomy affected bone
lengths. Preliminary analysis revealed significant differences in bone
growth between the intact and neutered groups. These findings strongly
support the need for an immediate re-evaluation of the current
recommendation to spay or neuter dogs to prevent or treat behavior problems,
and an equally pressing need to more fully examine the wide range of
physical effects of spaying and neutering pet dogs.
Figure 4. Fear and anxiety scores in neutered dogs compared with intact dogs
. A, all intact females (green) compared with all neutered females (red). B,
all intact males (green) compared with all neutered males (red). C, all
intact male and female dogs (green) compared with all neutered male and
female dogs. D, all intact and neutered females (open triangle) compared
with all intact and neutered males (open circle). In all cases, spayed or
neutered dogs had higher excitability
scores.
Summary
The above data is just a small sample of the significant data that were
determined in this study. By using large a sample of dogs than any used
previously to examine behavior in dogs, we found significant correlations
between neutering dogs and increases in aggression, fear and anxiety, and
excitability, regardless of the age at which the dog was neutered. There
were also significant correlations between neutering and decreases in
trainability and responsiveness to cues. The other three behavioral
categories examined (miscellaneous behavior problems, attachment and
attention-seeking behavior, and separation-related behavior) showed some
association with neutering, but these differed more substantially depending
on the age at which the dog was neutered. The overall trend seen in all
these behavioral data was that the earlier the dog was neutered, the more
negative the effect on the behavior. A difference in bone length was found
between neutered and intact dogs, suggesting that neutering has an effect on
bone growth, which may be related to other orthopedic effects documented in
the literature. Examination of changes in bone length of gonadectomized
dogs is continuing. | m***j

但是对狗狗来说就不仅仅为了避孕，因为狗不能像人类一样理智的控制性冲动和激素造
成的一系列行为问题啥啥的。所以要全部去掉？
我这么想的，也不知道对不对。

发帖数: 6775 | 6 结扎会让狗更agressive啊， 我家那位本来就够aggressive了。。。。 | s***s
发帖数: 7178 | 7 就算这个研究结果是可信的。去势与否也不是决定狗是否aggressive的唯一要素。
后天主人的指导管教爱护比先天的激素水平内分泌更能决定狗的未来。

发帖数: 6150 | 8 相比不去势的狗，可能还是去势狗狗的问题更少吧。不然干嘛大家都这么做。 | s***s
发帖数: 7178 | 9 这么做是为了总体利益
这个总体包括了宠物的一生，其后代的一生，主人的一生，还有经济社会等其他一系列
考虑
单从动物角度考虑去势是惨绝动物寰
但是就跟那个著名问题一样：
如果要你杀一个婴儿来救100人你干不干？救10个人呢？1个人呢？1个孕妇呢？100个罪
犯呢？
这种东西没有唯一正确答案
人类这么长时间以来的实践和磨合决定了一个通常情况下相对最容易接受的答案
这个答案不能让所有人永远满意
但是可以让尽可能多的人尽可能长久的满意
随着社会的进步，答案也在不以个人意志为转移的进步
比如现在不需要把老人扔山里来解决有限的物质资源消耗
那些时不时来炸版的人
吃饱了撑的耍耍嘴皮子站在道德制高点上质问别人为什么给宠物去势是一时的口舌之利
给宠物个安稳的家安定的生活生病了有依靠最后能寿终正寝不是冻饿受伤而死是一辈子
的事

这种基于问卷调查的研究一定要有非常仔细的设计方案，不是收了多少问卷回来excel做
出个p小于0.0001就行的。

可以减低某种癌症但是可能会导致其它健康隐患。
现在再加上行为上的研究，估计一时半会儿研究不清。。。 | x********u

这些个东东怎么测量呢？ 很难说用的方法是不是一定客观标准准确啊...
en, 反正我现在觉得做不做手术主人自己随便，反正不管做不做都得管好自家狗...

这样啊。那母狗spay以后是会更冲动还是更冷静呢？我胡乱地认为雌性激素会让狗更和
蔼可亲一些
的。
