7 Wonderful Giant Dog Breeds & Their Temperament

Before adopting the right breed, you need to have a look at a variety of factors. Size and temperament are important factors to consider before choosing the furry friend for your home. Large dog breeds are better suited for larger living spaces and homes with big yards.

Giant dog breeds vary in physical and behavioral characteristics. They may be large in size, but are usually gentle and affectionate to their owners. Many of them have a muscular build and make wonderful guard dogs.

However, some are too sweet to serve as guard dogs. Giant dogs are also prone to several health issues, such as hip dysplasia, gastric dilatation volvulus (GDV), wobbler syndrome, and hyperthyroidism. Giant dogs usually have shorter lifespans than smaller dog breeds.

Here are some wonderful giant dog breeds and their temperaments.
