Many animals actually do engage in kissing-like behaviours to show affection. These behaviours are so diverse, from dogs sniffing and licking potential mates, to elephants putting their trunks in each other's mouths. However, one animal kisses just like we do: the bonobo ape.
We share the vast majority of those genes with the mammalian species, but only humans (and occasionally our close primate relatives like chimps and bonobos) kiss. But the reason for kissing is still mostly a mystery, even to scientists who have spent decades studying the behavior.
As it turns out, bonobos are also big kissers. “Bonobos are known as the most amorous of great apes,” Kirshenbaum writes in her book. “They often use sex rather than aggression to resolve conflicts in their female-governed society.
It turns out that while dogs are pretty good at recognizing human emotions, they don't instinctively know what kisses are. We spoke with certified animal behaviorist Amy Shojai to learn how dogs experience kisses from humans. "Some dogs enjoy this, if taught what it means," she says.
When you kiss your dog, you might notice signs suggesting they recognize a kiss as a sign of affection. However, as puppies, this is not something they would understand. But, as dogs age they may associate kisses and cuddles with their owners being happy with them — as petting and treats often follow.
When you kiss your dog, you may notice signs that indicate they know that the kiss is a gesture of affection. As puppies, this is not something that dogs would recognize, although they would feel you doing it. However, as they get older they associate the kisses and cuddles with you being happy with them.
Seahorses flirt a lot
Their courtship ritual consists of a lot of tail holding, nose touching, and colour changing. But it doesn't end once they've mated. They continue flirting daily through the incubation period until the eggs hatch!
"They hug together and walk along in a little train." She says a bonobo in distress will reach out its arms for another bonobo, "and sort of ask for help."
Even a reptile, a hen and a fish look like they enjoy some human affection. From a bear that's as cuddly as a stuffed animal to a needy koala, and even this toucan, birds and animals alike appear to love human touch in these online viral videos.
Only around half of cultures kiss each other intimately. Central America, South America and Africa are particular regions where there is not much of a kissing culture. Only 4 of the 17 cultures researched in South America, 4 of 27 in Africa and 0 of 10 cultures in Central America lock lips romantically.
Some believe that kissing with tongue is a natural evolutionary progression that aids in mate choice. Others, citing cultures where kissing with tongue is not only absent but looked down upon, believe making out is a specific learned behavior that's gained popularity due to media consumption and globalization.
Electric impulses bounce between the brain, lips, tongue and skin, which can lead to the feeling of being on a natural “high” because of a potent cocktail of chemical messengers involved. A passionate kiss acts like a drug, causing us to crave the other person thanks to a neurotransmitter called dopamine.
While dogs and cats get most of the attention and applause, a rabbit is also one of the best pets for depression. They're extremely social and easily adapt to human companionship.

Pets as well as zoo animals form strong attachments to their caregivers. As attachment is a form of love, animals are indeed capable of loving their caregivers. Dogs have been reported to love their masters so deeply that they mourn their death for many years.
Generally speaking, dogs find close facial contact threatening, so you should avoid kissing dogs on their face, nose and top of the head, says Dr. Tynes.
