Training and intelligence
Start training as early as possible, because before long you will have a big powerful dog with a mind of his own. Gordon Setters are not willful and want to please, but have a strong instinct to follow scents, so persevere with recall training.
Temperament
The largest of the setter breeds, the Gordon Setter is loyal and obedient, once they have passed through the boisterousness of puppyhood. They can have a tendency to roam. They are good family dogs as they enjoy the company of children.
Attitude towards strange dogs and people
Gordon Setters tend to be reserved with people they don't know. This is not an aggression issue, he is simply very attached to his own people, but not that interested in others. They are not normally a problem with other dogs.
Grooming and shedding
The longer coat does need regular brushing. Gordon Setters are medium shedders.
Exercise
They have lots of energy and so need lots of exercise. Activities such as flyball might well appeal to this hunter's instincts, and Gordon Setters definitely appreciate free running.
Need for company
Gordon Setters adore their families and want to be with them as much as possible. This is a big dog, and if it is left alone to get bored it can do a lot of damage.
General
This is one of the dog world's athletes, so bear this in mind. Your Gordon Setter will love you dearly, but he will only be happy to relax in the house if he has oppotunity to burn off that energy.
