Baboons With Pet Dogs
The video below shows some fascinatingly odd animal behavior that I've never heard of before: baboons stealing stray puppies from their mothers and raising them as part of their troop.
This kind of interspecies interaction where one species raises another species specifically for companionship and protection--in other words, keeping pets--is behavior that is typically attributed only to humans. To see it happening with baboons and dogs is nothing short of amazing.
Warning, the beginning is a little difficult to watch, as a male baboon very undelicately kidnaps a stray puppy, but keep watching, it's worth it.
