Changes happen and it will be depends from the government to execute laws that can help to stop things like this, but the fact that we know inside that government there are many corrupt minds and it won't be hard to conclude that since we are still seeing places who continue to allow this kind of cruelty, it's either the government is not being alarm or there are part of this government who knows well if how money flows with this kind of gambling.
The fact is that many of the time, government in some countries have many things that remain unregulated and at that we have to understand that those countries which have no regulations concerning such things as gambling have open up the door for such activities that are outside some of the gambling rules in other countries that already have regulations in place, and one other thing is that, gambling I animals have been there for a while now, but people have only interest for those games that less risk and not too bloody for the unlookers.
But cock fight or dog fights are not popular because both animal have some element of wide behaviour that sometime could result into injuring their partners to the point of death without any regulation to prohibit that during the games.
For cockfight then i do believe that this one could really be regulated or would really be allowed, but for dog fight then this do usually happens underground yet there's no way that it could really be that allowed or would really be legalized considering on the animal that involved. This isnt something that do talks about livestocks or something that could be easily to breed with. This is why if we do tend to compare about dogs and roosters/chicken then it would really be that a different thing. Not really that totally shocking that tons of people would really be that going against with cockfighting which considering that animal cruelty is something that would really be a main issue with this type of gambling.
In cultural side of things which there are really that places on this world would really be having this kind of type of gambling which turns out to be enjoyable on trying out to bet
in between rooster on whose gonna win on having that fight until to death. Sounds harsh but this is something that some people do really love to watch or to see.
Therefore, if you do find this betting to be that totally brutal or harsh then you could always opt not to see but doesnt mean that it would be completely
stop and this would depending on countries jurisdiction whether it would be allowed or not.
