Excessive marking on outdoor scent posts. The behaviors described above can be attributed to male sexuality. The limited attention span will make any type of training difficult at best. If a specific behavior is allowed to develop and become an established part of the dog's routine, it may be difficult to eliminate. This does not mean that, if the dog is already exhibiting these behaviors, you should not bother to have him neutered.
Neutering does facilitate retraining of the dog.
More often than not, habituated behaviors can be greatly reduced or eliminated if the male has been castrated prior to the beginning of serious retraining efforts. Micky Niego, Companion Animal Services Courtesy of the Page last updated January 1, 1998.
