Dog fighting is a barbaric sport, but unfortunately it's only getting more and more popular.
In July 2009, the American Humane Society organized a raid to rescue hundreds of dogs from the fangs of dog-fighting rings. Of all the terrible cases these animal activists saw, one, in particular, has stayed with them: Stallone's torn-up face.
Stallone is just one dog among countless others who die slow and painful deaths when they're pitted against one another in the arena. The animals have no other choice: they're trained to be gladiators; they fight to the death.
Stallone's last moments are a heartbreaking reminder that these dogs aren't born aggressive. These "fighters" are really just normal dogs who need the same love and care as every other living thing. You can see the goodness in his face.
It's so important not to forget his story — to try and prevent more like it!
