I noticed a woman walking a Bull Mastiff that was not muzzled and was wearing a small collar. As they got closer, the large dog took three leaps towards Texas. She did not bark or growl. There was no indication that she was about to attack. She was no match for the woman who was walking her and pulled away easily causing her owner to fall. Molly, the large dog, grabbed Texas so quickly I did not have a moment to pick him up out of harm's way. He was in the mouth of this dog who violently shook him for a full five minutes.
