Puppy and Tortoise friendship.

An interspecies friendship is a nonsexual bond that is formed between animals of different species.[1] Numerous cases of interspecies friendships among wild and domesticated animals have been reported and documented with photography and video.[1] Domestication of animals has led to interspecies friendships between species that would never naturally exist together. In many cases of interspecies friendship, the species are not normally seen together, and sometimes, one is of a species that ordinarily preys on the other in nature.[2]
