"Yes," said the keeper, "there was a Dog who ate and  slept and played with the Elephant. The Dog went away three days ago."
A circus owner wants to transport his elephant, his dog, his cat and his mouse across a river. He can take one at a time across the river. But, unless he is there, the cat will fight with the mouse, the dog will fight with the cat, and the elephant will fight with the dog. However, as everyone knows, the elephant is frightened of the mouse, and if the mouse is present, the elephant will not fight with the dog.
This was uploaded a few years ago in 2014, but it continues to make its way around the internet gaining 2.6 million views. The clip was filmed at the Elephant Nature Park in Chiang Mai, Thailand and features a baby elephant playfully chasing a little dog around in the lush green grass. The dog seems to be saying “you can’t catch me!” while the elephant plays along until it gets frustrated. Upset that its stubby legs can’t move fast enough to tag the pup, it picks up a bunch of sticks in its trunk and shakes them, acting out one of the cutest hissy fits the world has ever seen.
this dog and elephant are best friends
That’s because Tarra is an elephant and Bella a dog.
For the most part animals tend to stick with their own kind, especially in the wild. Occasionally, though, when humans bring various species of animals together odd pairings will sometimes occur. Such is the case with Bella the dog and Tarra the Asian elephant.On the eighteenth month the dog approached the elephant questioning- “Are you sure you’re pregnant? We became pregnant on the same date ; I have given birth three times to a dozen puppies, and they have grown to become big dogs, yet you are still pregnant. What’s going on?”Both dogs and elephants are very social animals that live in tight-knit groups. Many of the elephants brought to the Sanctuary have bonded into 'best girlfriend' pairs. For reasons unknown Tarra the elephant has bonded with Bella the dog and the two have been inseparable. They aren't just seen walking around the grounds together, they actually participate in activities that socially bonded animals normally engage in: they eat and drink together and they sleep together. Bella (the dog) even allows the enormous Tarra to 'pet' her belly with her giant foot. Tarra is amazingly gentle with the dog and Bella, in turn, is very accepting of Tarra's affections. In the video of the story (below) you can see Tarra stroking Bella on her head very gently with her trunk, a behavior often observed in older female elephants caring for juveniles in the wild.  The Elephant-keeper did not care for the Dog, and he did want some money just then. So he asked a fair price, andthe farmer paid it and took the Dog away to the country.
