Do you want to know how old your dog is in human years?

You've probably heard that you just multiply your dog's age by 7 and that's all there is to it, right?

Turns out, there's more to it than that.

There's a few reasons for this. First, dogs mature fast in their early life. So the first year of your dog's life is more like 15 human years.

Also, the size of your dog plays a role in figuring out how old he or she is. Small dogs live longer than larger dogs. Different sized dogs may be considered "seniors" at different ages.

If you don't know your dog's age your vet should be able to tell with a complete exam. The vet will look for specific signs of aging for your breed to figure out an approximate age of your dog.

But if you do know your dogs age use the fun dog age calculator below and see how old your dog is in human years. Play around with the sizes to see how different sized dogs age differently.
