This is not legal in most places but theres talks of other animals fighting so why not ask.
I know it is popular with Bitcoin and gamblings.
Is anywhere such things exist?
Yeah there is mate and this is popular in some countries in Asia and I guess Europe as well when two Dogs either different breeds or the same(but mostly uses Pitbull)the dogs will fight until one retreat or dump already.and this is really a sudden game
I really don't heard about dog fighting only seen dog races which looks same as horse betting but never seen such game like fight between two dogs.
I won't bet as well even if it exists.
Yeah same here because I am a dog lover and I have couple of dogs with me ,I use to make them as family members and my family loves them also
