A mature intact male dog experiences a huge increase in testosterone. This gives rise to hormone-related behaviors such as:
urine marking in the house and outdoors
aggression towards other male dogs
territorial aggression
escape-oriented behavior to roam
Intact male dogs tend to have difficulty concentrating on tasks.
They may show abnormal behavior in the presence of a female dog in heat.
They may show aggression towards children.
FEMALE SPAYING BEHAVIOR BENEFITS
Females also have an increased risk of aggression.
When in heat, they may become moody and show signs of pain similar to human cramps.
Intact females also show urges to escape from the confines of the house or fence.
Increased urinations are also seen in intact females.
There is often considerable expense involved in whelping and caring for a litter of puppies.
Intact female dogs also tend to fight one another. If fighting becomes a habit, spaying may not resolve it.

Female dogs only invite mating when they are in heat.
