I wish I could walk in and see the hog every time before I send a catchdog. I'll send one from 100 yards and not even think twice...  
 think about it imagine running 100-200 in a sprint then fight mike tyson. 
If it was 1000-2000 yards I would agree but any dog that can't run 100-200 yards without being wore out I would not want to go in behind on a bad hog..
