Things to consider about large dog breeds

Despite reigning supreme with size, being big brings a lot of health problems. Larger dogs often have trouble with joints and managing a healthy weight. Large breeds are prone to osteosarcoma (bone cancer) and susceptible to other debilitating bone and cartilage diseases. The life span of large dogs is generally shorter than smaller dogs, often only living 6-10 years.

On the other hand, large dogs don’t typically need as much exercise as small dogs. They also can have very mellow and sweet personalities. For  these reasons large dogs ironically do well in an urban setting or an apartment.
