Actually, they tore down the pen the dog was in, so that dog is not coming back, nor are they likely to get another. My parents have no desire to go near them. However, as they live right across from us, they see him when he is out in the yard, so I'm sure they have seen him since the accident.
ETA: I just clicked on your profile to see your signature. What a cute dog! I have absolutely no problem with German Shepherds or other "dangerous" dogs (heck, dachshunds were recently named the number one most aggressive dog!). It's the owners who don't control or take responsibility for them that I have a problem with.
