Today I want to touch on a related subject – at what point is your dog considered to be a senior?

Obviously, this is related to my previous article since your dog’s aging is directly related to their size, but today we’re going to keep it simple.

When is a Dog Considered a Senior?

In short, larger dogs have shorter lifespans because they age more rapidly than smaller dogs.

Why? Well, science is still trying to figure that one out because it doesn’t necessarily fall in line with what we know about animals in general.

For example, compare an elephant and a shrew, the larger elephant has a much longer lifespan than the shrew. Research has shown, however, that within a species, the larger the individual, the shorter their lifespan. For example, a Labrador retriever has a shorter lifespan than a chihuahua.

The suspected reason for this rapid aging, though, is free radicals. (You can read more about this here.)

So when exactly is a dog considered a senior?

The answer depends on your dog, but there are some general guidelines that can help you to figure this out.
