Large breeds refer to dog breeds that typically weigh over 50 pounds and can reach heights of 24 inches or more at the shoulder. These breeds often have a sturdy build and are known for their strength and size. Common examples include the Labrador Retriever, German Shepherd, and Great Dane. Due to their size, large breeds often require more space and exercise compared to smaller breeds. They can be gentle giants, making them great family pets, but they also need proper training and socialization to ensure they are well-behaved and comfortable around people and other animals.
