Giant breeds refer to animals, particularly dogs, that are significantly larger than the average size for their species. Common examples include the Great Dane, Mastiff, and Irish Wolfhound. These breeds often weigh over 100 pounds and can stand more than 30 inches tall at the shoulder. Their size can be attributed to selective breeding for specific traits, often for roles such as guarding or hunting. Despite their imposing stature, many giant breeds are known for their gentle and friendly temperaments. They typically require ample space and exercise to maintain their health. Due to their size, they may also face unique health challenges, such as joint issues and shorter lifespans compared to smaller breeds.
