Evolutional pressure

Another factor that may be the reason why dogs age faster is considered to be evolutionary pressure that has been passed down through their genes as a way for the old dogs to make for your younger ones to survive interns of food availability, shelter, mating mates, etc.

That shows that size plays a huge part in deciding how fast your puppy would die and how fast it will age. So, if you easily get emotionally attached, and you’re want to get another dog, keep the size factor in mind. 

Diet and nutrition

The food your dog eats also affects her aging process and how fast she will age. Good dog nutrition has been noticed to help reduce how fast dogs age. Senior Dogs who were given senior food commercially manufactured had found in a study to live more than those who feed on non-senior dog diets.
