The rate of aging will increase if the dog is bigger or older. The smaller-sized breeds, like Chihuahuas, generally have a slower rate of aging, and larger breed dogs, like Great Danes, are more rapid to an age when compared with dogs of different dimensions. This basically means that the larger your dog is when it is full-grown, the quicker its body ages. Larger-breed dogs usually do not live as long as smaller to medium-sized dogs, but there are always exceptions.
