Male or Female:
What should it be:
Not only Males may mark their territory; both sexes, when left intact equally mark their territory .If you raise, train your puppy properly, and when neutered at the appropriate time, both sexes will forget about this and make wonderful companions. A male, even if neutered, may mark his territory, if you bring in a female ; he actually marks for her!!
A male typically has a better coat, although it is the genes who determine the amount of coat your puppy will have. Both sexes can have equally nice coats.
Who is more affectionate?
Both sexes can be sweet and loving, It is common though that the little guy is more inclined to be in that "loving" category. Females tend to be more moody, even when spaid. A boy is most likely more focused on it's owner, wanting to please, where the girl is more "independent".
Males tend to be more loyal, since they have the greater desire to please you. They may be a bit easier to teach and train ,and therefore, the better choice for a companion as well as a show or performance dog.
