It is no surprise that our canine companions age faster than humans. Some studies have found that our pups are similar in age to a 30-year-old human by the time they reach their first birthday. By four, the dog is nearing human middle age at 52.
A new study suggests a dog's body size, age, and weight may influence the health ailments your pup may develop over time. The find, published today in PLOS ONE, is part of a more extensive nationwide study of how dogs age over time and its effects on their bodies.
