The Powerful Story Of This Big Dog, Little Dog Best Friendship Will Melt Your Heart!!

Meet Harlow and Indiana, the adorable two-some who landed a book deal out of their human's Instagram account @harlowandsage.

Their story wouldn't be complete without first mentioning Sage – that is, after all, where the name "Harlow and Sage" comes from! Sage was Harlow's older sister who went to doggie heaven just last year at the ripe old age of 13.

Harlow was in a deep despair until the humans brought home the spunky, hilarious Indiana, a pint-size doxie with an ENORMOUS sense of humor.

Now Harlow is the big Weimaraner sister, and Indiana is the spunky lil' sis that you just have to see to believe. We've added some of our favorite Harlow and Sage moments below for those of you who don't have Instagram. You can also keep up with the dynamic duo via their website, www.harlowandsage.com. (But remember, the little one's named INDIANA!) Enjoy! And don't forget to SHARE!!

Here's the original duo, Harlow and Sage...

Sadly, Sage went to doggie heaven last September at the ripe old age of 13.

"Harlow would like to introduce her new little sister!" the caption read a few days later!!

Harlow and Indiana are almost always on the same page...

ESPECIALLY when it comes to snuggles.

They both love Meryl Streep movies...

Although Indiana is way more into dancing...

Harlow's is much more of a travel enthusiast!

Gotta go...New adventure awaits!!
