Are you sure this is real? Dogfighting obviously is, but I can't find any outside substantiation of this idea of dogs fighting in the trunk of a car with "thugs" blaring their music at the same time. I can't find anything from the Dallas PD about it or any news source.
This was on the facebook site of the vet clinic we use- the East Dallas Chamber put out a notice of the noise program but nothing was mentioned about this type of dog fighting. As I posted I'd never heard of something like this before and it sort of surprises me because dog fighting isn't common in the sector area of the city they are testing the program in, so I"m baffled too! Northeast Dallas just doesn't have a dog fighting issue- southeast and southwest do.
ETA: we don't really have a loud noise/music issue in the northern part of the city, so yes, I"m baffled by this. Even if it's all true, calling 311 (the non-emergency number) won't do any good because the backlog is weeks and months long!
