im sorry to tell you, that i saw that dog bite the gretzs puppy on the face, and they both were on leashes, they just got to close to on another going for a piece of food laying on the ground, the bigger dog ( bart ) went after the puppy ( bradly ) and it went from there
so i wouldnt go off on those dogs not having leashes and every other dog i saw had a leash on, i even saw a cat with one so i dont really know what you were looking at
