Large Dog Breeds Large and giant dogs are among my favorites. Large dog breeds weigh approximately 60 to 90 pounds. You’ll need plenty of room for a large dog, both inside your house, and in your back yard. Many large dog breeds are prone to hip and elbow dysplasia, and osteoarthritis. Large dog breeds also don’t live as long as many smaller breeds, with an approximate life expectancy of around 12 years. Choosing a large dog breed can mean saying goodbye sooner than if you choose smaller or medium size dog breeds.
Their large size often makes large dog breeds susceptible to hip dysplasia and related conditions, like giant dogs. They can also be susceptible to heart conditions.
