Giant dog breeds are imposing animals that, contrary to what one might expect, usually have a calm and balanced character. However, their size implies specific requirements in terms of space, nutrition and veterinary care.

Special care for giant breeds

- Exercise: moderate but consistent. Excessive exercise in puppies can damage their developing joints.
- Life expectancy: giant dogs live less than small breeds, generally between 7 and 10 years.
- Health: they are prone to hip dysplasia, gastric dilatation and heart problems.
Feeding giant breed dogs
A high-quality diet adapted to the dog's size is essential to maintain its joint and muscle health over the years.
