There Is Always Somebody Who Cares
These guys met each other when Bonedigger (the lion) was only a cub. His handler, nicknamed Joe Exotic, said that Milo (the dachshund) and his litter mates accepted Bonedigger into their crew partially because they sensed that something was wrong with him and that he needed help. It's almost as if they knew that he had metabolic bone disease which rendered him mildly disabled. These unlikely friends are spending so much time together that sometimes Milo even tries to imitate his growls. Must be hilarious.
