Despite the fact that dogfighting is illegal in all fifty states, it is, however, still taking place underground!
Dogfighting is cruel and causes severe injuries and deaths of thousands of dogs every year in the U.S. Most of these dogs die slowly, and very painfully while wallowing in their own blood !
Frequent police raids are required to crack down on the perpetrators. Further, a severe imprisonment penalty and a substantial monetary penalty would be a good and viable solution.
