In general, small dogs are expected to live longer because they have a faster metabolism. Because of this trait, large dogs will grow old faster. Experts cannot explain the reason behind this. But if a large dog grows up, the process might lead to abnormal growth of cells. The dog might even develop cancer or other diseases and die.
A small dog can expect to live up to 14 years. Thus, small dog breeds like a Shih Tzu, Pomeranian, and Chihuahua will have a longer life span. On the other hand, large dog breeds like the Labrador, Great Dane, and Saint Bernard might not live as long.
The dog’s body size will also affect the life span. Some large dog breeds do not get heavy, they may weigh up to 50 pounds. According to experts, dogs that are over 90 pounds can expect to live up to 8 years. On the other hand, dogs that weigh less than 45 pounds can expect to live for more than 10 years. But even if small dogs don’t get heavy, they will have health issues.
