I just got off work and had to take the Boxer dog for a walk( she won't let me sit down until I take her), so we get around a couple blocks and were walking next to an elementary school, baseball practice was happening and we're walking by. I hear sounds of a dog collar with tags, so I look to my left and there is a blue pit, eyeballing my dog and starts to charge. It took off from the porch and as soon as it got to middle of the street, a guy I had just walked passed washing his truck, nails the dog, running it completely over. I seen the impact of the truck then had to look away, heard the "thump, thump." the dog ran back to the house but one of her rear legs is shattered... I'll check tomorrow to see if the owners took it to the vet... it was terrible... One of the owners was holding her child in the doorway as it happened but didn't notice the dog coming after us... terrible
