Size and character describe general tendencies. Individuals vary with age, health and background.
Daily life & exercise
Offer steady walks, sniffing and suitable play rather than pushing endurance exercise. Take particular care with heat and growing puppies.
Coat, grooming & everyday care
Brush the short coat and check facial skin, nails and teeth. Plan for large-dog food, transport and veterinary costs.
Training & living together
Teach cooperative handling, loose-lead walking and calm visitor introductions before the dog reaches full strength. Do not encourage guarding behaviour.
