Further evidence is in that dogs really really are the best.
A beagle in Australia adopted a baby possum after losing her litter of puppies.
This is an unbelievably cute story of differences being overcome by love.
Molly lost her puppies at birth, but just a few days later, welcomed a new baby to mother.
A baby possum jumped on her back and has been holding on tight ever since.
Poss, as the aptly named critter is called, was abandoned by her mother.
The two now hang out on their cattle farm in Victoria as a bonded duo.
Molly even waits under the tree where Poss sleeps during the day to keep a watchful eye on her new baby.
