This adorable German Shepherd, Dunder, goes from being a teeny puppy to a one-year old dog in just a matter of forty seconds.
This is a time lapse video showing pictures of Dunder growing up. This is so much like seeing your very own child growing up before your own two eyes that it just makes you feel nostalgic and sentimental.
Why do they have to grow up so fast? Watch Dunder’s little journey from being an eight week-old puppy to a full grown German Shepherd. Just a little warning, it will make you reminisce your own dog’s years with you, too.
